squares slide away from paddles when placed

[idr1ss]

squares slide away from paddles sometimes when placed, completely invalidating rules. this happens alot and gets super annoying sometimes when it happens to everything you try to place.

hey can you figure out how to reliably reproduce it? then i could do a fix :)

1. Make some rules for an atom of your choice. I used sand for this one.
   
2. Move one of the cells on the left side out.
   
3. Put it back.
   

Edit: If the square doesn't slide, repeat steps 2 and 3 until it does.
