Erro nos corpses dos pokémons. [POKEEXP.LUA]

Olá, desculpa se estou postando no local errado.

Meu servidor, está passando por alguns bugs, e um deles, é que quando eu mato alguns pokémons (só alguns, como rattata, magikarp, caterpie, etc) o corpo some.

Eu já chequei no configuration.lua se o corpse está correto, e já chequei também se no xml deles está correto, e ambos estão, entãofui ver no console, e deu este erro:
