Feudal Weaponry [FORGE]

Should fix error that leads to crash on dedicated servers. Please tell me if there is still a problem. Thanks!

Edit: Tagged it as 1.16.5 too (was only tagged as 1.16.4 before). However, I have not tested whether or not it actually works for 1.16.5, but at least it is available for 1.16.5 in CurseForge so you can try it out!
