Found if I used a hopper as a landing in the middle of my stair case I get stuck in the hopper and have to jump around to get out. Issue happens going up and down staircase. Tested with wicker, ladder & Hatch filters (in all other situations I have been able to walk across without a problem).

Normally has two streams /waterfalls crossing the staircase but I dug everything out to make sure there were no other conflicts. Did not test stone but assume same issue with the lip of the hopper and the lip of the stair not lining up to make a solid item.
