hey all, long time no see. i once again must seek your ultimate wisdome (actually im only talking to WadeV here haha)

PROBLEM:
ive finished part of my map, ive compiled it. but when i start JAMP and i "/devmap mymap" the game crashes.............HOWEVER
this problem does not happen if i "/devmap mymap" in JASP.

What is going on? how do i fix it? is this problem going to be perminent unless fixed now?

Well you've put in your title that it's an MP test, but you're doing it in SP.

If it's multiplayer, simply write an arena file and create a levelshot then you can load it from the JA Menu.

If it's MP you don't need the / before the command... I don't think.
