One thing to try is to reauthenticate with the mod menu in the game. You can force this by deleting the following folder on your computer and restarting the game:
C:\Users\%USERNAME%\AppData\LocalLow\Landfall Games\Totally Accurate Battle Simulator\modio-152
Right-click on the Start button, and choose ""Run"" (Windows 8/10/11) or press WINKEY + R
Type, or copy and paste the following into the Run box: ""%userprofile%\appdata\locallow\Landfall Games\Totally Accurate Battle Simulator\"" including the quotes.
Delete the mod.io-152 and/or the modio-152 folders
Restart the game
Once you restart the game and navigate to the mod menu, you should be able to reauthenticate to mod.io, which should hopefully resolve any conflicts
or issues.
Should this not work, your best bet is to reach out to the TABS developers directly at support@landfall.se
