I too am crashing like crazy also.

I crash either during the third level of an expedition or immediately after turning it in if I get to complete it. I wish it would just hit me on the first level.

Edit: Removed solarfall from my bar and did a test expedition with no issues. Still have to give it a few more tries in case it was a fluke, but hopefully that's all it was.

same game crash 3rd expedition during boss fight or immediately after u hand in expedition

4 times we could not end expedition , several times people got stuck in walls and tru the floor , and all the times unable to get credit and exp reward...

if you have solarfall in your skills - that still cause crashes ... if you have it try to remove and see what will happen ...

if you dont have then , no idea
