[Defense / Survival] Hero defense help.

[Plunders]

Hero Defense Horde, is my first prjoct in warcraft 3 edidor (practised on some other maps though.)
It may seem noobish but: there's a -sp (singleplayer) function in my map, however last night i tested it once more, and as i was solo'ing top lane, a invisble pack actually emerged from the bot lane.

Since i'm new i don't have an idea of what's wrong.
You can either fix the bug and re-upload it to me
Or if possible tell me what to do.

Either way i would love to know how to fix this error.

Thanks a lot.
And (if i am allowed to say so) +rep to the dude who helps me

Mr. Plunders
(considering uploading it in maps, so give me feedback, if it's too noobish there's no reason for me to upload anything)
