Hi, I hope I can get some help with this. When I try to start a new world with this mod and repixture, it thros the following error, when I try to start the server:

AsyncErr: Lua: Runtime error from mod 'rp_armor' in callback on_joinplayer(): ...\Roaming\Minetest\games\repixture\mods\rp_armor\init.lua:429: attempt to get length of field 'slots' (a nil value)
