Probably caused by both of them because neither of the mods have been updated in over half a year.

I think this mod (or Virtuality Overhaul) is causing my game to crash. He's part of the error in the log... this error repeated for every single empire.

[15:00:20][trigger_impl.cpp:1200]: Script Error: Invalid context switch [from] from United Flusionian States [country], file: events/giga_000_achievements.txt line: 607, Scope:

It works!
