Memory Management Fix

In recent weeks I've found out there were some memory mismanagement going on in my resource packs, and I just finished the work to fix that. This is more of a "better safe than sorry" fix, as the previous version worked just fine, and it would probably only be an issue in very rare cases. For the RPG Elements pack, along with the memory optimization, the "icons" display options of the Experience behavior now works even if you don't use a fixed experience requirement progression. 

Redownload the pack to get the latest version.

Happy Stencyling!
