Backpack slot not visible on players back and inventory slot is the missing texture placeholder.

I am playing multiplayer with only 2 people using ESSENTAIL Mod

I had this same problem, thank you @realzguy. For some reason, Prism Launcher didn't pull Trinkets as a dependency for me with the Fabric version, so maybe there's something wrong with the way it's listed?

It's optional, so that's probably why it didn't pull it.

Thanks for your response. :) Do you know if the missing texture could be resolved without adding Trinkets then?

nevermind i didnt have trinkets
