Plusemu Room bug.

So ok, Theres an wierd bug on my hotel, where if you have 199 items in 1 room it's fine but if you have any more than that it bugs I've actually sat in a room and tested that^.

anyway I've heard it's in the SWF but I don't think it is as it does this

Where as if it was SWF it would show the furni or let you even add it?
Anyhow Thanks anyway, I have really no idea what is causing this lol.
