When I've opened my inventory in creative, after dying in survival and flying back to that position in spectator, Minecraft crashed with the added Crash Report.
I've changed from spectator to creative because the first try I changed from spectator to survival about one block above ground and died immediately because of falling damage. I do not know if this is an already known bug - I do not report that because I cannot reproduce it in other worlds.
In contrast to MC-125506 I was standing on land in a village.

What I expected to happen was...:
The creative inventory opens.

What actually happened was...:
For a short moment a blank inventory window with the same size of the creative inventory opened, then minecraft crashed.

Steps to Reproduce:
Not sure. After loading the world again, most of the items (but not all of them), I recollected where lying on the floor again - at the exact same positions as they where before, but my position was the position of the crash. The crash did not happen again.
