I've noticed this with every common infected replacer, theres this one guy in a suit thats only present in L4D1 campaigns that doesn't seem to have a model to replace him. I saw him a couple days ago but idk if you fixed it or not, as I haven't seen him since.

I think I already fixed that. There were 2 models I didn't think needed replacing because they were labeled with test and weren't in any of the testing maps.

Ah, thank you, great mods btw! (Hope we get some high quality survivor and SE models from you in the future)
