Redstone on top of block entities breaks when loading a structure

Please upload the structure file used in this example.

Done, the commands basically trigger a meteor shower using fireballs

For me 9 hours ago was like 4am so that is why i didn't respond

apparently if you load the structure again it doesn't break the redstone so it might have to do with redstone loading before the blocks

this affects /place and structure block LOAD button but not redstone-powered structure blocks, see

Still happens in v1.21.8, and I noticed that some other blocks do the same thing when being loaded from a Structure Block manually (not via redstone), being: powered rail, detector rail, activator rail, and also carpet (but only if 2 are touching, even if different colors), and also leaf litter.

Blocks seemingly NOT affected are comparator, repeater, sign, (regular) rail, lightning/end rod, pressure plate, button, fence/gate, door/trapdoor, string, torch (regular/soul/redstone), candle, twisting vines, daylight detector, creeper head, conduit, scaffolding, lantern (regular/soul), cobweb. That's all I felt like testing.

I think the migrated comment above from 13/Oct/20 6:17 PM has a good point, so maybe Structure Blocks need to be loaded in 2 “layers”, being solid blocks first, then ones that require supports (i.e.: something underneath). Just my opinion. It’s weird though, because having other blocks, like bricks underneath doesn’t cause the issue, only certain function blocks, like hoppers, command blocks, etc.
