I'm sorry you closed this already, but the bug has still not been resolved. It still does not function properly. Clearing the cache does nothing. It's still confused woth world resource packs and region packs. Yes, a different resource pack will now download in a region, but then it stays stuck on that resource pack, even after clearing the cache and quitting Minecraft. The only way to fix it is to restart the server, but then you still have the same problem. Whichever resource pack loads first stays, regardless of whether its the world RP or the region RP.
