So I have an iron farm i built in 1.15.2, which worked great and got me 5 1/2 double chests of iron in a few weeks. after updating to 1.16.1, it doesn't work anymore. the only change i could find was that villagers no longer need work stations, which mine had because of 1.15.2, but even after taking them out it didn't work. does anyone know why it isn't working?
the design is the same as mumbo jumbo's in hermitcraft season 7:
only difference in mine is the pickup system and there are no workstations anymore
