This error doesn‘t help ^^ You should send the client console and server console log, so that we are able to help :)

Yeah, dumb me. :D

I think i found the error in the console log:

File exists in two addons - possible conflicts! lua/ulib/shared/hook.lua (ULib and [TTT] Player Info/Role Counter)

[ERROR] gamemodes/terrortown/entities/entities/ttt_role_counter/init.lua:33: attempt to perform arithmetic on a nil value

It seems there some conflicts between this two in the lines above mentioned addons. I do not understand why its loading sometimes and sometimes not. Should i remove both addons?

UPDATE:

"File exists in two addons - possible conflicts! lua/ulib/shared/hook.lua (ULib and [TTT] Player Info/Role Counter)"

I disabled the TTT Player info/Role Counter. Didnt know that there is already a info/role counter in the ulx pack until i saw the console. I think at 03:00am i was too tired to think far enough xD

Now its working flawless. Thank you for ur great help. And thank you for ur work on TTT! :)

Glad that it works for you :)
Thank you and enjoy the game.

There is no role counter in ULib. Any error with Ulib and „conflicts“ is just an hint for an error in the other add-on that is not ULib (if I wanna explain it easily). It‘s just the TTT Role Counter that ist buggy. We already have a Role Counter / Role Distribution and Killer Info add-on. You should give a look into the other TTT2 add-ons :)
