is there a maximum custom units you can create??
because when i was creating i couldnt create anymore and then i delete one unit and it could create again? help pls
it could be 2 reasons
1. there really is a limit
2. u put so many custom units in the map that made the map over 4MB (bnet doesnt allow traffic of a map bigger than 4MB), so worldedit stopped u from creating more units
Yep you can only get 100 custom units. If you use up too many custom units then you'll just have to get rid of some or start modifying the original units.
