because its bugged, something went wrong, cuz if you test ur map from world edit itll crash... its something im not sure, try askin some veteran members
Hahahaha... Not really. I hate it when my maps get corrupted. I haven't really found any way to fix this other than to copy everything to another map. If someone has troubleshooted this problem b4 and came out with an answer (I haven't), then feel welcome to rebuke my primitiveness.
If no player slots appear, then that means that there is a syntax error in the script. Either in the map script or in an imported Blizzard.j . You can try to extract war3map.j from the map with WinMPQ and check it with PJass (http://amai.wc3campaigns.com/pjass.zip )
I get a Virtual machine, can;t find main class eor when i try to run that, and i got the version of java that it linked me to, do you have any other checkers?
