Crash in Arena Lobby

[Chelleste]

Couldn't find any previous post about it so here we go: I had this several times no ... I have the F7 clan recruit running and I am in arena lobby, someone seemed to have applied to be invited to clan and I want to check who what is, so i click on the icon on the upper right corner and ... poooof ... game crashed.

 

I normally don't have crashes, so I guess this is really related to the above described situation.

 

Cheers :)
