Bug/Glitch with multipli CS's

[The chaser]

First. Was just a question if it's fixable
Second. I ordered the original game already(Takes up to damn 2 weeks delivery, Couldn't wait playing yet), that's why I was curious for a answer on my second post: Will it be fixed with the original game, if not I still need a solution

Plus, that seems like a name problem. Maybe the game "thinks" those stairs are there, instead a wall. Try re-naming or the stairs or the wall. But, I don't know if that will work. )I know that for modding reasons)
