[HELP]Invisible Wall in Maze

OK well I got this invis wall in maze and I have no idea how to get rid of it.
It blocks passage to one of the rooms. Anyone have any idea how to get rid of it?
I tried figuring it out myself but, I can't figure out how to find where these wall files link to.
I know my way around the client, I just need a boost to find the right files.

look in the brick file maybe?

perhaps redcell?

it wont be redcell, thats for stuff outside the map boundaries. Its not what stops you from getting there.

can you give a SS?

Make sure it isnt a REDCELL
