[Fixed 1.05][Bug 1.04] Game Crash - Power Station choose upgrade

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

I’ve also encountered that one. I won’t give that much details but i doesn’t seem to be bound on OS, nor display resolution, nor the map size since i’m running on Windows 7 Professional with 1920*1080 and encountered it on the mega factory one.

I didn’t accelerate time until powerplant research was completed and the game crashed as i tried to select upgraded from a power station.

thanks, I’ll fix this!
