I tried making a very simple spell to move a column of up to 8 blocks from the block I look at in the axial direction I'm looking at.
If I cast it on said column, it doesn't do anything - but it also doesn't throw any errors.
This is also the case for a single block, floating in midair, no matter what side I cast it on.

I also tried just using the caster raycast as a Target as I thought it may need absolute and not relative coords, but that also didn't work.
