and just wanting to state emc made no direct changes to gaining EXP/farm spawning for this update. Vanilla internal code changes would be responsible for spawning behavior changes. Witch farms breaking is due to the same issue every major update that structure saving was disabled, however we have re-enabled it (with improvements) so new ones wont break on 1.9. Someone suggested the idea of 'restoring' previous farms, which is something we can consider but would be low priority... as it would require extensive research into the code to do so.
I had a feeling it was a 1.8 change... Either way, the farms I posted are way faster anyways. I just need to decide what design to use
