hi, I just created a server rust, I have doubts that I hope will solve:

1: in my server makes me install three types of rust (rust + +, oxide, and a third I can not remember) I for now i installed only oxide , Which one should I install?

2: : Players on my server tell me that just placing the foundations of wood, they are destroyed instead of metal ones not, how do I fix it?

Tranks all
