My scmd pops up with the message that if I add another location, saving in the ""SC vanilla"" format wan't be possible. I don't no what this format is, just as why i'm not allowed to ignore this message (it simply reopens when i agree in adding another location)!
HELP NEEDED
Please note that I have only 54 locs on my map yet.
SC vanilla format is the origional .SCM format, before patch 1.04. After patch 1.04, more editor functionality was added, such as additional locations, and certain hero units. This format is known as hybrid.
Why, however, your scmdraft 2 would believe that the map is a vanilla scm is beyond me, unless you have starcraft 1.03 or lower installed somewhere. It is also strange that your editor is giving you a message when you hit 55 locations, it was more than 63 locations (not including anywhere) that wasn't allowed in vanilla.
Basically, as long as you open it with an up to date copy of starcraft, and only edit it with post 1.04 editors (which are virtually all editors out there), then you should be fine.
