That's a visual bug. There was someone who came along and was fixing a bunch of bugs recently and just sorta assumed that was one of the ones that got fixed lol. Guess I still gotta get to it.

ok, thanks for a quick response

Sorry, just processed the mod version, this should be fixed in the most recent versions.

That's now fixed, thanks
