Version Information

Forge version: 36.1.0
Psi version: 1.16-93

Trick: Move Block Sequence doesn't seem to work on certain blocks, it looks like it's mainly blocks that are mined with pickaxes but dunno how snow fits into that.

I tested a few blocks and these are the results

Blocks affected:
Log, Dirt (All variations), Noteblock, Planks, Glass, Ice (All variations), Haybale, Large Mushroom blocks, Glowstone

Blocks not affected:
Iron Blocks, Piston, Cobblestone, Nylium, Ore, Snow Block, Sandstone, Endstone

Can confirm. Can't add much more information, but I can confirm it.
I can add slightly more information! Here are all of the blocks it does work on:
All types of dirt, all wood type blocks, wools, tnt, sponges, (soul)sands, gravel, clay, glasses, light blocks, mushroom blocks, hay bales/target blocks, ices, slime/honey blocks, wart blocks, concrete powders, honeycomb, and all psi blocks.
