I've been playing on V1.1.5 until today that I've downloaded V1.2.3 and this never happened to me before. I also tried playing through the game with the same seed on a new save file and the MAV still occurs. If anybody knows of a way to fix this please let me know.
Other tested fixes that haven't worked:
- Right click the .exe file, select 'Run as Administrator'.
- Right click the game's folder, select 'Properties', untick 'Read Only', click Apply, then try running it.
- Right click on the .exe, select 'Properties', go to the 'Compatibility' tab, set compatibility to XP Service Pack 3.
- Kill "taskhost.exe" process in your task manager.
- Try running the excutable directly instead of using shortcuts.
