I just downloaded black powder red earth just to check and it doesn't crash for me. The way Go Quiet works is by removing voice lines from the vanilla and ARES .xml files. It's copies of the original files with less content. So I can't imagine how it could cause a crash unless there's something in the original files that would crash like a reference to a missing sound file. Since I haven't seen any crashes at all yet, that seems unlikely. My guess is your crash is caused by something different.

Can you reproduce the crash?
