I have created a webpage to conveniently view crash dumps, and it is probably a bit better than using a JSON viewer, I guess. http://pmt.mcpe.me/crashdump/ How to use I guess it is so very obvious. Just paste your crash dump into the box in the webpage. Just remember, do NOT paste the lines like Code: ===BEGIN CRASH DUMP=== They will not work. For the rest, find out yourself.
So i am gonna try it out! so don't say that the error is on a plugin.. just testing Fantastic! it works perfecty..
