I play Wilhelm and I mostly use lasers. I recently came into the possession of a Maliwan shock blaster. I shot at a Lost Legion guy at Vorago Solitude and the game hung. This happened also with a Firestarta at Regolith Range firing at scavs. The fact that both weapons cause status effects makes me think the crash bug has to do with status effects and Cold War reacting badly. I’m using a Celestial Enforcer COM, if that helps.
I’ve always noticed that ice tends to “freeze” gameplay a little, especially when shattering with RoboPunch.
