Hello guys, I need some help.
Im trying to find way to limit changerace.
For now, player can change race every time they want (for example, they start with Human, then change into Orc during 1 round)
I want to change it so race will change only after death or new round.
I know there is somthing like that, becouse i saw it in translation files, but i cant find CVAR for that. Can someone help me?
I tried to search in forum, but i didn't found it :/

"You will be {racename} after death or spawn"
   {
      "#format"   "{1:s}"
      "en"      "You will be {1} after death or spawn"
         }

Thank you for help in advance

Yep it is, they can instant change race during game
Like, im human ill teleport there, and change race into somthing else coz i can.

Ohhhh, okay, thank you for straighting it up
