See if this old hotfix .jar for Nex prevents the crash.
Is the special task force must be in independent mode?
When I'm playing, the game starts to warn that not being in independent mode will cause an error.
What's the exact error text?
The warning I remember is when a task group starts acting independently despite not being in independent mode; I thought I'd fixed all such cases already, but the log will have a stack trace whenever the issue reappears.
The game hasn't crashed yet.
But the text at the bottom left shows a warning
Here is the text.
