I just came back from a few weeks break and of the teleportation tiles I use to access the different stories and rooms in my house, three out of four have stopped working. In more detail: I cannot walk onto the tiles, just as if I was walking into an invisible wall or something was blocking the tile. Of course I checked and no items are located on the tiles. Strangely enough, the fourth teleporter still works fine and takes me where it's supposed to. I also tried to go into house customization mode to re-place or remove the tiles, but I can't enter customization mode. I just get booted under the house sign and get the "Preparing house. This may take a few seconds..." message. There might be house addons interfering, like my parrot or fountains, but alas, they are in the upper stories which I cannot reach without the teleporters! Anyone got any hints for me?
