I am using DarkRPG 1.0 addon along with these others https://steamhost.cn/steamcommunity_com/sharedfiles/filedetails/?id=806806862
[ERROR] A runtime error has occurred in "lua/darkrp_modules/levels/sv_data.lua" on line 14.
The best help I can give you is this:

Warning! DarkRPVar 'xp' wasn't registered!
Please contact the author of the DarkRP Addon to fix this.
Until this is fixed you don't need to worry about anything. Everything will keep working.
It's just that registering DarkRPVars would make DarkRP faster.

Hints:
- No hints, sorry.
