Just so you are aware (back when we were having the same issue on 3053) despite the never-ending loading screen, apparently your avatar does actually ‘physically’ load in-world (despite you not being able to see it) and this does actually reset your decay timer. Though obviously only for the immediate place where you are loading in.
I was sceptical about this at first, but it seemed to work, as my base was still standing way before they paused the decay timers, and it had been over a month at least.
When they did finally release the ‘fix’ (I use the term loosely, because evidently it seems the bug is still here in some form) I was taken aback to find my base still standing.
Sadly others were not so lucky.
All that being said, just logging on to stare at an infinite loading screen for twenty minutes or so just to stop your base from disappearing is pretty far from ideal by anyone’s standards.
Hope it gets fixed for everyone pronto, and you don’t lose everything.
