Also I noticed that the issue with the ores looking like stone until block updates is still present in this version as well.
Saw some freshly generated ores without the issue so maybe it's leftovers from 21? Idk.
I hadn't tried build 22 until today, but I saw small ores in the Nether that looked like overworld stone, even though I hadn't been into the Nether with build 21, so I find the "leftovers" explanation doubtful. Back to build 20 for me.
Edit: I'm also having a little trouble with the High Pressure Lava Boiler (in build 20), but I'm not sure whether it's a bug or something I did wrong: I used an IC2 fluid/solid canning machine with fluid ejector upgrade to empty some lava buckets into some large bronze fluid pipes leading to the boiler, and it seemed to work initially (the front of the boiler changed texture to indicate it was running), but now even though the output tank of the canning machine has 1259 mB of lava in it, which indicates that the pipes are full, the boiler isn't heating at all.
Edit #2: I figured out the lava boiler problem - I had forgotten that the boiler itself could output steam into the pipes. Now I put in a shutter module to prevent that, and it's heating up fine.
