After many years of using my floor-to-floor teles in house they won't let me walk on a few of them anymore. Details- First floor has 1 that goes to 2nd floor this one works. 2nd floor has 3 (one from the1st, and 2 others that go to 3rd and 4th). I am unable to stand on the 3rd and 4th floor tele. I have also noticed on first floor I'm unable to stand on tile where the 3rd and 4th floor tele are on 2nd floor. Unfortunately, I can't put into custom because I have Items that would need taken down on inaccessible floors. Does anyone have any ideas what's going on? They have worked for yrs and just recently had this issue. Thanks!
