It seems that you added Optifine, perhaps that is the cause?
Also, Hexxit II's Sphax patch has been updated! I recommend you to update to the latest version: https://bdcraft.net/community/releases-for-packs-f10/technic-hexxit-t598-s130.html#p47029

I'm unable to reproduce this issue so I'm not exactly sure how to help. Does it occur on other 1.12.2 modpacks, such as Tekkit 2 or The 1.12.2 Pack?
