Custom halflife.wad is allowed?

I have a little problem. I play NGHL. Sometimes I just freeze in place. It doesn't matter when, in the air, I walk, I do an object boost, I just freeze in place, but the timer and other entities and objects move, what needs to be done to solve the problem, nothing hinting at the problem is written in the console. Sorry for my english ❤️ HELP PLEASE
