Blocks misaligning video included

Can anyone tell me why all my pieces are perfectly aligned in forge and yet as soon as I start a game everything is out if place. Best description of the issue is for example, I have 2 invisible blockers connected. Walking g over them in forge is fine but in customs it is too far out of alignment to just step over, you literally have to jump to get onto the next block.

Another visual example I can give that I have just thought of. For those of you who have played jenga saga (4 tower variant of jenga), you would have noticed that one of the bridges falls down before the round even starts. Now I’m assuming this is the same problem I’m having as I’m sure we can all agree that those bridges are perfectly stable in forge.
