This issue might not be a major one (and this is probably why nobody ever mentioned it, to my knowledge) but it's still a problem.
The snakeskin rug is supposed to have a higher priority than all of the turfs except the carpeted one, and this is indeed the case in the game, however it always appear small on the minimap, while it should also appear a bit on top of other turfs it dominates, as per usual in this case.
Thanks for reading.
Steps to Reproduce
Plant a snakeskin rug on top of other turfs it dominates Look at the minimap
