I thought I had undid that move I made in SCEE since I wasn't sure if there was a feature mapped at the new location and this was an archived feature (SCEE doesnt currently show post box POIs, but it does ask about collection times.)

Looking at the map on browser, I don't see a box at the right location. If the location of the move I made then undid is still recorded, I think the post box should be moved there.
