Hello i think found another crashing bug caused by choosing select upgrades on a power plant
Steps to reproduce
Open Production Line
Start Game - Medium Map
Build a bunch of research centres
research power production
accelerate time until completed
Place a power plant
click on power plant and select choose upgrade
Crash
Game running windows 1680*1050 - Win 10 X64
(this happened to me when i was installing power plants for the first time for a game already in progress)
This was the only line in the errorlog
