when using several spells with the warlock wand, do not count it acts like a hoe, and I get these errors in the console, has some problems with the icons of the wand store minecraft and spigot 1.14.2

this happens for example when using the Hat spell

The Hat spell will be fixed in the next dev build, thanks for pointing that out!

The appearance shop looks OK to me, though. Are you using the default RP? What are you using to show the shop?

And the Warlock wand is not actually a wand. It's just an item for Warlock mobs to hold.

Update: I wasn't checking the magic sword, that model should be fixed now- thanks!
