The message from console is shown when i take it.
and as far as i can understand player_spawn work normal, player_hurt doesn't work and ultimate_on doesn't work either

And maybe that will help when i enter the server with that race chosen i resieve the message "invisibility set" though that must be shown only at spawn

P.S before that problem I had another one in my player_hurt p==0 it said that variable was used earlier than assigned after that I wrote global p in every loop where i had p and get this error. But then I deleted them again i didn't get that problem again and still has this one
