I have a very similar crash report with a lot of similar information in the same places but I'm not sure if it should be considered a separate issue. I can replicate the crash by clicking on the creative menu search feature, that's true, but the crash also occurs sometimes when the menu or inventory are not open and I am travelling quickly into unloaded chunks (I have a crash report for that circumstance). Should I post the crash report as a separate issue or inside this one?
