I have a creep summoner as a building and i need it to summon units instantly. Problem is the "stats-units trained" requires a buildtime of at least 1 and that slows it down i want it to build instantly, so i moved the units to "stats-units sold" This works good and all but when i try to upgrade the building to a completly different set of creeps, the building model file changes however the creeps are the same, they dont change to the next tier. I have checked the list for the next tier and its correct, plz help.
