I am unsure of what Versions this affects as I play on Windows 10 and run my realm off my PC, yet all of my friends are on Xbox and notice this same issue, which I would assume the realm is on 1.10, not 1.10.1. The issue is that in a series of levers that lead to iron doors, the redstone will get stuck on/off and I have to go through and break all of it to get it to work. I have a 7 digit code lock for a vault door that didn't seem to break, but the series of doors before getting to the vault all had the redstone break and I had to manually go in and fix it all. I noticed it is similar to some other reports, but not the same issue. Hopefully there is a simple fix to this bug as it can get quite irritating to have to break all the redstone repeaters on 4 tick delays every time I want to open the doors.
