When holding anything in hand and interacting with a block the corresponding tool is auto swapping into my character's hand...
which means i am unable to use the pro pick or choose which pickaxe i want to use when mining as its constantly swapping to one pickaxe in my bag. I have tried scanning the wiki and controls list but nothing seems to come up with what is causing this.
I am using mods and can provide that list if I am just not missing something so obvious...
