I'll see what I can do highhead.

I have other missions that last much longer...as long as 24-36 hours without OOM crash.

This mission consistently is dropping between the 60-80 min mark.

Leads me to believe that it could be a CUP Terrains or CUP Units issue as the mission uses CUP and 3CB (use 3CB in several other mission without issue)

Just spitballing here but I'll see if I can reproduce in vanilla mission.

I'll do a pure vanilla in the next couple of days and let you know Highhead.
