[1.7.2] Inventory being cleared on world reload

chimera27 · April 26, 2014

I've come across a problem in my mod that is proving VERY difficult to debug. On a somewhat rare occasion, the players inventory is being wiped on world load. I have no idea what is causing it, it doesn't seem to be random though (opening/closing a world repeatedly a large amount of times did not produce the bug). If it generates some error it's not present in the games log files. The only thing I know about it is that whenever it happens, my first try opening a world will fail. What I mean by this is I will try to open a world, and it will go right back to the title screen. When I try to open the world again, the players inventory is empty. Has anyone encountered this before or does anyone have any ideas on what I should try? I can supply any classes if needed, and again, it doesn't produce an error or anything of the sort $:-\$

EDIT: Managed to track down an error log:
