[justinrpg]

 i created like 50 buildings totaling 120mb so i used dat packer on them... now is 118MB... the problem is now several large file B.a.t.s when plopped they disappear in a second then SC4 crashes to desktop , does this on 7 b.a.t.s, (so far that i know of), the seven are all my creations... and i only used datpacker on all my large file b.a.t.s (1-4mb files each model)
