Need help with skulltag Please [stairs]

Ok so I am making a new map, and there is no errors in the map and Ive been mapping for quite some time now. I made some stairs and for some reason when I get to a certain stair ill fall through the floor. Not all the way though, kinda like water or something. Ive had this problem before and figured out how to fix it and now I cant remember how to fix it. Anyone have any ideas?

Any help will be appreciated!

I'd imagine that you perhaps accidentally tagged the offending stair to a tag used for the transfer heights special elsewhere in the map. If that's not the case, I'm not sure what the problem is.

You could try getting some screenshots of the map and/or the problem in-game. You could also consider uploading the map to a temporary site for others to examine.

Nvm. It was the node builder acting funny. I fixed it. This thread can be deleted.
