Sometimes can't start campaign mission 3

Can you provide some more information about what happens when you try to start mission 3? Are you seeing any errors, does something not load, etc. The more details the better it will help our devs look into it.

Can you please try using a different launch setting and see if that fixes it? https://support.playstormgate.com/hc/en-us/articles/27719297725083-Which-option-should-I-choose-when-I-launch-Stormgate

Glad to see it's working!
