So all of a sudden any helmet I place onto the armour stand just doesn't show up on it. When I try to retrieve the armour I do get the helmet back, it just doesn't show up on the stand. I am using a fair few mods so I'm sure that has something to do with it, it's just weird that it's suddenly become a thing.

Has anyone else had this happen? It's not a big deal at all but it would be nice to fix:)
