This Drawbridge Seems to be bugged for me!?(Fort Deadlight)(anyone else?)

So this is after i completed the Merchant and the Pirate came to the Isle i hit the lever and drawbridge went down , but then after i reloaded map lever was unvailable and drawbridge was up but collision was acting as if i can walk through set Moveable Drawbirdge Mesh ty!( Its a matter of Aesthetics that after i pull the lever the drawbirdge should stay down ty!( and or vice versa if i pull again drawbirdge should go up!))
