Stop sending the same crash report. You have to wait and be patient.

Also, fill out the information. Without that information, Cray won't be able to do anything,

He won't ever fix this if you act like this. You didn't fill out the information you were supposed to so he can't fix the issue.

Can't see any traces of Furniture mod in crash report stacktrace

At the bottom they have the furniture mod installed. Cray already looked at the crash and said it has to do with the mirrors.
