Could you erase the NBT data when I release a mob? I use an auto-inventory-sorter which groups the mob-catchers based on the currently used & the left over NBT data (ie. last mob that was released NBT & the current 'used/full' NBT data).
It makes it hard to find empty mob-catchers (I need to wait for the 'twinkling' colors in order to see which mob-catchers are 'in use/full' vs empty).
Thanks for this great mod too!
