Hey there Ramza, huge thanks for adding the feature, I think that will really allow some nice polish for people using the plugin. The plugin is however crashing any time I select a character from the equip tab. I tried a bunch of things to see if I could get it to work but it crashed every time.
It crashes on actors with or without the new tags. It crashes no matter where the tags are, ie. Actor box, class box or both. I moved the plugin order around as well and no change.
I'll post an image of the crash report for ya.

Edit: the image doesn't seem to be showing up, I'll post the console. Also when grabbing the console error I noticed that after I moved the plugin down in the order the crash on people without the new tags wasn't happening, I had to get the crash from an actor with the codes.
