Ladder issues - I'll try to be concise.

1.) Place Library Ladder furniture.
2.) One player stands at top of ladder in such a spot as to block a second character coming up the ladder.
3.) Second character goes up the ladder and is blocked, goes down again.
4.) First player moves away.
5.) Any attempt to climb up the ladder remains blocked while ladder is in the same X-coordinate position.
6.) Rolling the ladder left and right does not fix this.
7.) Moving the ladder through furniture controls DOES fix this.
