Custom models kicking ppl?

[Kofi_Banan]

I made map with araund 80 custom models and .I start the game and evrything is ok,but after some time models are changing colours and playing random animations(portrait instaed of stand) when it happens usually i got lags , warcraft stops working and i have to use alt+ctrl+delete to back to windows and turn off w3.
any idea why?or how to fix that?
