[PROBLEM]MobArena i crash ;(

[macio443]

Siema ! Mam problem z Mob Areną... Gdy wszystko zrobie:

1. Zbuduje Arene
2. Dodam /ma setregion p1,p2
3. Dodam warpy /ma setwarp lobby,spectator,arena
4. /ma checkdata
5. Wszystko gotowe... Wpisuje /ma j i wchodzi normalnie...
6. Wyłączam serwer
7. Konfiguruję Config.yml
8. Zapisuje, włączam serwer
9. Wszsystko ładnie...
10. Wpisuje /ma j i wypierdziela błąd "You don't have permissions for join any arenas" (przecież mam OP i Admina :/)
11. Chce zrobić wszystko od początku i wywala "An internal error" i wyskakuje w konsoli:
