I've been playing on Survival a lot since the reset yesterday. I haven't seen in monsters and I haven't had any success breeding cows, sheep, or villagers. Is monster spawning and breeding disabled on Survival?
When it comes to mobs spawning, that seems to be normal. Might have had something to do with the lag earlier. And for the breading, it's most likely a bug. I have passed this over to the management team. Should be fixed momentarily.
