Alright so if you haven't noticed yet or if you have, my resource pack is incompatible with this version. Here is what Mojang had to say:
Here is the link if you can't see the image: Mojang.com. I am currently in the process of updating it and will release it as soon as I can. I will try my best to make sure everything is working to the best of my ability. Also anything that is similar in this new update that has something changed in my resource pack will also be changed in the new update, i.e. arrows. Hopefully I can get as much of this compatible as I can, but thats not to say Mojang may change it in the foreseeable future. If anything changes and my resource pack becomes incompatible again, I will try to fix it again. If Mojang changes it back to how resource packs worked in 1.8, then I will have that ready to be updated and post it as soon as I can. If I miss anything, then post a comment here, head over to the about page and post a comment there, or on the other websites that I have it for download. The other websites are as following:
