Re: [hlcoders] [Source] Thread-safety ?
I find that hard to believe tbh, It kinda never broke before, and now it breaks all the time, even with thread-safe functions implemented or threading completely disabled. If you're doing something un-thread-safe, like calling game functions from another thread, you can expect it to break. The fact that it didn't break at some earlier time is pure luck.
