Hello Jonatan,

when i am trying to load all treatment units from a simulation using Regwise i am getting this error message. "Damage risk data potential basal area already belongs to this data table". the treatment units is not loading and i am not able to click on "select variables". but i can see simulation output from single treatment unit and i can select the output variables for one treatment unit. any idea on what is causing this problem?

0000812: Change: Removed Cudafy from HabitatModel

Fri, 20 Feb 2026 13:40:15 +0100

The outdated package Cudafy was used when evaluating Habitat models. The package is now removed. It should not have any side effects.

Trodde detta var åtgärdat med bugfixen. Men inte?

0000808: Incorrect version handling of final felling and thinning delay values

Wed, 28 Jan 2026 14:05:36 +0100

Final felling and thinning delay control table variables' units were changed from period to years.
However, the conversion of values between version were done incorrectly, making some values not convert correctly.
All values should now convert correctly from period to years.

0000807: The result variables for growth data are not correct for Checkboard management

Thu, 15 Jan 2026 11:22:33 +0100

The result variables for growth data (CAI) are miscalculated due to the assumption that one year can not have multiple harvests.

0000806: Wrong coefficients in tree age functions

Thu, 08 Jan 2026 08:31:08 +0100

Wrong coeffecients are used for rich and poor in the method TreeAgeWithoutStandAge

0000805: Blir ingen gallring när Thinning Delay Max sätts till 0

Fri, 19 Dec 2025 16:10:13 +0100

För beståndet sker gallring i period 2 och 3 och slutavverkning i period 6 om Thinning Period Delay Max = 2.
Om Thinning Period Delay Max sätt till 1 blir det gallring i period 2.
Om Thinning Period Delay Max sätts till 0 blir den ingen gallring alls.

0000803: Problem med gallring i bestånd med flera provytor

Fri, 19 Dec 2025 15:26:52 +0100

FMPP-bestånd med flera provytor ger inkonsekventa gallringsresultat

0000802: Önskemål: Tillåt sparande av TreatmentUnitLog som tabell i resultatdatabas

Önskemål: Tillåt sparande av TreatmentUnitLog som tabell i resultatdatabas

0000801: Önskad funktionalitet. TIllåt specifika trädslag i UserDefined-result

Tue, 25 Nov 2025 09:12:25 +0100

Jag vill kunna redovisa volym RASE (Rönn, asp, sälg, ek). Ek och asp finns som egna trädslagsgrupper, men sälg och ränn ingår i OtherBroadleaveas.
En lösning vore att tillåta att ett User Result definierar för specifikt trädslag (Species) och inte bara trädslagsgrupp. Undrar om inte denna funktionalitet har funnits tidigare?

0000531: Feature request: let user define LastThinningYear as none

Tue, 25 Nov 2025 09:03:02 +0100

Hej!
Hur kan man ange i beståndregistret att ett bestånd är ogallrat? Om LastThinningYear saknas tolkar programmet det som att gallringshistorik saknas, men om man uttryckligen vill ange att beståndet är ogallrat, hur gör man då?

Mvh Peder

0000799: TPG missar gallringar?

Thu, 20 Nov 2025 15:37:27 +0100

Bifogar exempel där det borde gallras i period 1 när man kör med periodmitt, men av okänd anledning görs det inte.
Grundytan är hög och enligt bakomliggade gallringsmall (SKS) borde det vara hög gallringsprioritet.
Relativa åldern är inte för hög och inte heller övre höjd (dominant height).

0000798: Report Template selections are reset between sessions

Thu, 13 Nov 2025 13:13:49 +0100

Selections should remain between sessions and be specific to the project.
Should be implemented similarly to how result variables are handled.

0000796: The order of map layers makes a difference when calculating intersections in the Initial State --> Map view

Wed, 12 Nov 2025 10:43:11 +0100

To get the correct behavior, the 'Stands' node needs to be down furthest down the Map Layers list.
However, there are a lot of problems with the map currently, better solve them in a more stable .NET8 Heureka release since other libraries are used there.

0000781: StandWise 2D and 3D maps are not consistantly updating correctly to changes

Wed, 12 Nov 2025 10:26:20 +0100

If the tabs are not in focus, sometimes the events don't fire correctly, causing the visual data to be out of sync.

0000797: Thinning Delay is given in periods but would be better if it could be specified in years

Wed, 12 Nov 2025 10:24:47 +0100

It would be more accurate if it could be given in years. This change has already been done for Felling Felling Delay, so this change should be similar.

0000784: Adding "/" to report name when copying a report throws unhandled exception

Wed, 12 Nov 2025 10:24:29 +0100

We should add or improve input validation for filenames of reports.

0000787: Incorrect view of optimization results for simulations with same names

Wed, 12 Nov 2025 10:24:17 +0100

If the same result database is used in multiple projects and simulations have the same name, the optimization results are displayed under the "wrong" simulation when "display simulations/optimizations from any project" is checked (General Settings).

Optimization Results --> Tables and Graphs result view

0000792: Missleading error message on importing stand register with random data

Wed, 12 Nov 2025 10:24:00 +0100

With a csv file like:
Treatment Unit; Treatment category; Alt No; NPV; 0; 1; 2; 3; 4; 5; 6;
Bestånd - 0; Blandskog med förlängd omloppstid och ökad hänsyn; 1; 31583; ; ; ;Th; ; ; Th;

You get the error message: "StandId Alt No has higher impediment area than total area ". Should probably be something like "not a valid stand register"

0000795: The treatment unit data does not update if there is a domain filter selected in TPG Results

Thu, 06 Nov 2025 11:19:28 +0100

Under the tab 'TPG Results', if a domain filter has been chosen, even if it's the same as the default, then the treatment program data doesn't update anymore when changing treatment unit ID.

0000753: Add search function for pricelist and result variable settings, and improve existing search function for control tables

Wed, 29 Oct 2025 09:56:23 +0100

There currently exists options for searching through the numerous control category settings. However, it is rarely used by users.
Improve accessability of this existing function and similar functionality where it fits.
