Walking.Walk(Tile tile) stuck at lumbridge stairs

[jamesst78 0]

is there a certain reason that walking.walk() gets stuck at the lumbridge stairs when walking to the bank on the top of the castle? I can't seem to know how to overcome this problem , it keeps right clicking the stairs on the first floor and can't seem to climb up to the second,

PS. I'm a beginner scripter but I'm decent at java and programming in general as it's my bachelor's degree.
Thanks in advance

Had the same problem what i did to fix is that i check if i get to the walking spot with getLocalPlayer().getDistance() <= 1 so that it has a margin

This does get you into new bugs tho
