Possibly related to the next-to-water bug, Link cannot move up or down when directly to the left or right of an unwalkable ladder combo. Links acts as if there are unwalkable combos above and below him. Link can still cross the combo with the ladder, and he acts normally when the ladder combos are only above or below him.
Link reacts to Ladder combos when next to them [655]
For all of these bugs, please indicate if Z3 movement is enabled or not.
Z3 movement is disabled. This bug occurs on both a 2.10 quest and a quest updated every build. I'll see what happens when Z3 movement is enabled.
Edit: Bug does not occur when Z3 movement is enabled. Only occurs if Z3 movement is disabled.
Still present in build 660.

This is an unpassworded quest made in 660 from the default template. It shows 3 bugs. The ladder bug is demonstated through both ladder and water combos, and shows what happens based on what ladder Link has.
Based on this quest, the following is true and can be confirmed about this bug:
Only happens when Z3 movement is disabled.
Nothing happens if Link does not have any ladder.
If Link has a basic ladder, he cannot move vertically when there is a ladder combo to the left or right of him.
When Link has a level 2 (advanced) ladder, the bug does not occur.
However, if Link crosses a ladder combo diagonally (starts to cross the pit, and then exits by turning 90 degrees), the next time he approaches the ladder combo, he gets on the ladder too soon (try it in the room the Lv.2 ladder is in).
Link only reacts to combos he can cross the ladder with (I threw in hookshot only combos just to test that).
The ladder combo must require the ladder to cross (a walkable water or walkable ladder combo will not trigger the ladder, and thus not trigger the bug).
Fixed in the next build.
Bug is confirmed dead in build 668. Thanks, this was a bad one.
