Drag and merge the folder with your gamedata folder, override the original file if needed, you know it all by heart anyway...
Temporary fix for the crashes caused by << xr_reach_task.script:57: attempt to index a nil value >>, which has not seem to have a public fix for it in several years, and since this might not be the best solution I am open to all suggestions for improved solutions
In principle, it should work for any CoC-based modification that does not alter the file << xr_reach_task >>, and in the case that it does, the fix can probably be adjusted to be compatible anyway.
Some strange behavior is expected to be observed from NPCs or Squads, but keep in mind when you see such strange behavior, at least your game is still running and not crashing.
E: 09/09/21 - Some changes made to address an issue reported on the Anomaly version of this fix.
