This started occuring after this latest patch which changed the storage UI.

Sometimes when I open my storage either through fairy or through manager it opens up far to the right with half the UI window off the screen. I am not sure exactly what triggers it, but having to move it constantly is fairly annoying.

I have been getting the same thing and tried figuring out what the issue is, thought it was my horse at first because the horse UI will randomly move and has been doing that as long as I can remember.  I use UI HUD scaling at 83% and know that I will get random issues with certain things pertaining to UI and just chalk it up to my scaling being different than normal.  Novas just having a presence near me will cause my UI to fragment occassionally with whatever passive effect is going on with them.  Have a screenshot of me getting the bug during grinding, could be a whole slew of things causing it.  Stuff happens when you try and work through old game code as a developer, just depends how bad or annoying the bug is.  I did you guys the favor in censoring my guild chat because they are naughty devils.
