The mound bed bug seems to me to be bad enough for a rollback, along with a fix.
I've got withered crops, and trees moving into winter.
Most people's compost budget doesn't involve enough mulch to feed each winter mound bed 6 or more mulch per real life day, and I think my observed consumption is higher than that. So a lot of people will have no choice but to experience a pre-moundbed winter, if this isn't at least fixed promptly.
With my fodder crops withered, and no way to keep production working till winter ends or the bug is fixed, I figure I'm at high risk of sleeping livestock.
Back before mound beds, sensible players stockpiled fodder. Now sensible players run a more just-in-time system. I'm paranoid, so I have some reserves, but I'm really not sure they'll last.
I doubt you can un-wither the crops and un-winter the tree farms without a roll back. Hence my suggestion that world 16 loses 11:23 of game time, plus however long it takes you to notice this request, taking us out of winter - and keeping us out - till this bug is fixed.
