In the basement of the mansion that I’m using as my base, the sewage pump tiles all have mail boxes on them. I seem to remember there was a recent change that added more mail boxes to places, so I guess this bug was introduced then…

Thanks. Found this place - fix is on the way.
Thanks!
It’s Zaraga Tiles, which is an updated version of Xotto’s tilest, along with Xotto’s Cosmetics mod… 
Hi,
has the fix for this been added yet? I thought I saw it somewhere in the update notes (via the launcher), but I’m still seeing the mail-boxes on top of the sewer pumps in my mansion basement. Or will it only fix new areas that I explore?
With the new map memory system (which I’m not sure I like that much), the tiles look as they should do, when you can’t see them, but once they are in sight, then the mail-box appears again… 
It will only fix newly generated areas. I updated to the latest experimental, and new mansion didn’t have that problem. For me it seems to be working fine now.
Awesome!
Thanks for letting me know…
