I have a problem, when I use a custom player skin, steam say me : Bad file consistency, but yesterday, the skin was good ... what happend ?

Was it when you tried to connect to a server? i think servers can force file consistancy so you cant connect if you are runing custom stuff.

this happen to me be4 when i have making custom models i blamed it on 1.1 rofl btw did the numbers work? ud never pm me back :(

I'm sure this is down to the hitboxes, if they are different from the default and the server has set file consistency to on, it won't let you join. I've never known it happen with weapon models, it's just player models i've found a problem with, which makes sence.
