OptiFine causing crash; continued error after delete​

Launcher Version:

1.4.3​

Modpack:

The Ferret Business​

Modpack Version:

Details of the issue:

I tried to support my game by throwing in OptiFine to the pack, but it caused it to crash. I've disabled it, but it still crashes. Same thing by deleting the mod from the folder.

Note: The console said something along the lines of "caught exception from fluxedCrystals"​

Have you tried reinstalling the pack? Might have been a modification by optifine that caused a file to change to something the rest of the mods did not like (because mods have feelings and emotions too!).
