I'm playing the Feed the Beast 1.12.2 Ultimate Reloaded mod pack with the addition of the latest 1.12.2 versions of the gravestones mod, 5zig mod, secret rooms mod, doggy talents mod, and Optifine, but whenever I try to downgrade my Optifine from version Optifine_1.12.2_HD_U_E3 to anything else, the game will crash. However, updating to a preview of version Optifine_1.12.2_HD_U_E4 or deleting the mod entirely loads the game up just fine. I have the latest version of Forge for 1.12.2. I also have the crash log in a pastebin below. Anyone know what might be causing this?
