Same issue here as #4602 / #4608 also present in AE2 7.0.0 and 7.0.0 beta2 for MC 1.15.2

I believe this is also causing problems in ATM5 in 1.15.2 using 7.0.0 beta2. I've updated the pack to the release version of AE2 (7.0.0) and receive the same crashlog

No longer crashes, can set some recipies. One that didn't work was attempting to set to blank pattern. Clicking button seems to do nothing.

Will investigate more in about 2 hours

Fixed in 7.0.1 (hopefully): https://www.curseforge.com/minecraft/mc-mods/applied-energistics-2/files/3038720

Nevermind I'm just dumb and can't remember recipies. Fix looks good so far. Thanks!!
