[Bug]: Creative tabs disappearing, taking JEI recipes along with them

[Corn-on-the-Orb]

Steps to Reproduce the Bug

I launch my modpack up normally, and when I go into the creative menu, the game freezes for a second, but when it does load the creative menu, one or several tabs are gone from the menu.

Expected Behavior

All recipes and creative tabs should be there

Actual Behavior

Creative tabs disappear and also remove recipes, whilst the items do still exist and can be crafted or obtained in other ways. This seems to vary with the amount of RAM allocated and just between launches. Yesterday the tabs were there just fine, today they arent, I allocate more RAM and another one of the creative tabs disappear
