I have done my first time munge on a map. It is stuck on: ifs_movietrans_game.lua (which I have no idea what it is, so I looked for it and found it). I know you are NEVER EVER EVER supposed to stop a munge, but it has been stuck for several hours. I got off to play on my 360 for most of those hours, and still nothing. Anyone know what to do?

Task manager, kill visual munge, manuel clean and remunge. I stopt often the munge when trying mungeing fonts. It doesn't kill your map, but you should do an manuel clean after that.
AND make sure you killed every task. For example the fontmunge has an own process.

If you have still problems with the munging, are you doing an shell mod?? Or custom ingame??

Stopped munging. Did manual clean. Game now crashes.

and the error.log....

It's fine. I can just load it as a shipped map, hopefully that will work.
