0.4.6 Wont add to EMC when the item has already been learned and does not have enough emc to produce the item

When adding an already learned item to the transmutation chamber when you don't have enough emc to pull that item out results in the system lagging then rejecting that item and adding it to a storage cell instead. Not sure what is causing this. Downgrading the mod to 0.4.5 fixes this issue entirely.

I am running a slightly modified version of FTB Sky Odyssey where I have updated all the mods to the current versions with the exception of Modular Diversity witch is 1.10 and I added Equivalent Integrations. All is working intended with 0.4.5 installed but not with 0.4.6.

REPRODUCTION

1. add item to transmutation tablet or transmutation chamber to learn the item.
2. remove all of that item till you cant take anymore out.
3. add the item back in through the AE/RS system.

this will result in the issue. If you remove all storage except the transmutation chamber from the network then it wont even accept the item at all but will still cause lag.

I would provide a log file...however it does not make any mention of this happening in it.

Also getting this in 0.4.6. and I'm not using a modpack. It's ignoring AE priorities. Doesn't seem like this mod is being actively developed anymore though.
