I am not sure if this is really a bug or what or even that serious but it is moderately confusing. When trying to make a potion keg, one of the necessary components (according to the assemblies menu) is a keg tap. But when I go into the parts menu I don't find a keg tap but a barrel tap. Now I found out they are the same because I was able to create a potion keg. I just found this moderately confusing for a minute since they weren't named the same and I haven't made a potion keg in forever.
