trying to create a magic item, but the magic item type box won't let me select anything. As it's 'necassary' I can't create the item. 

Magic Item Type only matters if the “Base Item Type” is “Item” and not “Weapon” or “Armor.” If it is “Item,” did you start with an item of a different base type as the template?

yeah, I was seeking to make a weapon, though after refreshing a couple times, and reloading up the homebrew it went through. Where before it was telling me one of the fields I couldn't select had to be filled out. Was first time encountering this issue. 

It happens once in a while where it gets stuck on thinking it’s a different base item type than has actually been selected.

ahh cool thanks
