I was trying to auto-craft awakened core on DE for 1.12.2 and server crashed while ejecting core. I am using AE2: UEL Extended and catserver core.

UPD:
Tried the same setup on earlier version (1.0.0.11 instead of 1.0.0.12) and crash did not happen

Should be fixed in 1.0.0.13

Yep, now it works. Thanks!
