So, on Realms we've started a world and set up in mushroom fields. I've got a few villagers in a big wooden box, with a ton of beds (4 villagers to about 20 beds). I keep throwing potatoes in there, and the villagers display the hearts, then thunderstorms, but I can't work out which conditions I'm missing for breeding.
Secondly, I've got an iron farm (based on wattles design) which is on the ground, and iron golems intermittently don't spawn. I'll get about 2 stacks of iron, then it will just stop for ages. Then next time I log in it might work again for a while. A 32x32 area has been covered in buttons so the iron golems can only spawn on the platform (and they only ever spawn on the platform now) and I've used spectator mode to check the caves under the farm but I can't see any spawning there.
I've put these together because they might be to do with being in the mushroom fields? I've not really had these issues before.
