[FIXED] [V1.29c 04 AUG 2023 - Geoscape] Crash on EventGeneration: System.InvalidOperationException: A fatal error occurred during Update[] - Operation is not valid due to the current state of the object

[GreeboCherry]

I attach save from day 15.
Crash happens on my three attempts to play from it.
From this save going on speed x4 and dismissing all pop-ups about completing works at base, on day 19 around 4:00-6:00 there is crash with following stacktrace:
