Hello there! I am having an issue where after using little hammer on any block, it becomes walk-through-able, unless they're a perfectly shaped cube.

Minecraft version: 1.20.1
Little tiles version: ALPHA_v1.6.0-pre098

Here is an example of a cube little tiles block working perfectly:

And here is a random non-cube structure thingy:

I am using other mods as well, here's a list:

P.S. Everything else seems to be working fine.

Wanted to update this, as I have managed to find the cause of the issue,
It was a mod called "Radium Reforged", as removing it removed the problem.

I tried to figure it out but just could not. Glad you found the issue!
