Bad plugin

[Dos-e]

So, its EmptyWorld causing errors and the crash?

What I'm saying is, you didn't need to provide a background of every error you're seeing on your console.

Well im showing what the console said and all those errors were brought together I wasnt aware of which one was causing the crash. The crash dump is above for someone from pm to review.
