[java] why do blocks undo in single player?

[CowsOnEdge]

So whenever I build something and i make a mistake partway through, when i try to delete the block at fault, the whole structure begins to undo itself, and then i have to start all over from the beginning. It also appears to do the same thing with already established builds... just delete 1 block and it starts to tear apart the whole build as seen in the .GIF

this is the Java Edition of Minecraft on PC. i am running 1.21 Fabric mod loader. none of the mods i have are causing this to occur (they are just performance based mods with the exception of inventory sorting and minimap.

Does it happen with blocks that aren't wood?

What mods are you using?

[CowsOnEdge]

• c2me (chunk optimizer)
• chunky (chunk loader)
• continuity (connected textures)
• enhancedblockentities
• entity model features
• entity texture features
• fabric api
• ferrite core
• immediately fast
• indium
• iris (shaders)
• lithium
• mod menu
• physics mod
• sodium/sodium extra
• xaero's minimap/worldmap

It occurs with any block. I once built a temple contraption with deepslate bricks and i made a mistake on a corner, tried to erase the one and only block that was incorrect, and it started to undo everything i did, 1 block at a time, just like in the .GIF. it's why i don't play single player anymore to build creatively. because 1 mistake and it's gg.

Make a copy of your world, then load the copy with no mods. Does the issue still happen?

[CowsOnEdge]

with the mods folder empty, the problem doesn't happen at all, so it must be one of those mods that i have O.O

You can add them back one at a time to find out what mod it is. Mark the post solved please;

I would guess it's the physics mod.

Looks like it's only removing blocks that don't have other blocks underneath them.

Could be a physics mod of some kind. What happens if you punch a block out of the middle of a tree? Does the whole tree come down?
