Describe the bug
Since the upgrade to v34, the crafting calculation slowed way down and even caused a server crash (only into HV, so probably crazier in higher voltages)

To Reproduce
Slowness was shown anytime I was starting a new autocraft (at the time, I was making 3 HV Macerators, a Drawer Controller and a Drawer Slave)

Expected behavior
No slowness and no crash

Additional context
Gist Crashlog

Environment
Omnifactory dev build: fa485e6

• Minecraft Version: 1.12.2
• AE2 Version: appliedenergistics2-rv6-stable-7.omni-fixes-v34.jar
• Forge Version: 14.23.5.2847

Downgrading to v33b brings back the normal swiftness of the crafting calculations and have not had a crash still had a slowness

EDIT: Maybe...might go back to v32b

Definitely no crafting calculation slowdown on c3b1dea

Downgrading to v33b to see if the issues go away.

Sorry about that, i committed an unfinished branch on top of v34. Should be back to normal on v34b

Cool, i'll do some testing

Update for anyone who reads this, solution was the disable substitutions on crafting patterns. After doing that, every crafting plan calc is instant.
