First, to be clear, I’m referring to this:
https://hearthstone.wiki.gg/wiki/Battlefield,
and ‘Bonus features’ in particular.
Some time ago, coins in Stormwind (from UIS, not the original) stopped working, I think, and can no longer be tossed, unless I messed it up.

Recently, I’ve also noticed that the bell on The Grand Tournament grounds no longer prompts food or drink delivery.

I don’t like the direction in which the whole shebang with battlefields is apparently going: first, no longer a new one for every expansion, then bugs seemingly progressing…
If you’ve noticed some other features broken, feel free to post them here, I might add them to the collection and compile a list, if needed.
