There's a game bug, where the beds just simply say; "this bed is obstructed", this may be seen as a player mistake but in reality its really bugged. The beds where it's located inside a house are obstructed, I removed it and placed it again, changed its location where it originally was, changed materials and nothing!

Another one where it appears to be in a cave were working perfectly fine, until when we were experiencing the bugs, they bugged out too!

We've discovered that for some strange reason, after the bed were placed in a completely different location like the outside), they work fine! but after 2 or 4 clicks, they simply obstructs.

This originally happened it in our realm.
