Heyo, thanks for the great pack!
We recently updated from 0.3.18 to 0.4.2 and are running a fresh install of the server with no files pulled over from the old version.
We have found that vanilla lava farms using dripstone are not producing lava, but were in 0.3.18. Any info on this? Did we miss a mod that altered this functionality? the cauldrons shown here went the entirety of yesterday unfilled (with players nearby, in real time) and went overnight chunkloaded and still no lava.

Fixed in v0.4.4
