Unfortunately that is a known bug. Not sure what causes it, but it's not uncommon for peoples game to crash as the nether is unloading. So it's not just you, and it's not cause of the baby creeper.
Well, thanks for answering - I was kinda out of ideas as to what kind of keyphrase to use at the search engine and just didnt bump into any reports of it being known.
Also, for anybody interested, I got my "Nether Exiting" fixed.
Don't know how exactly. I did all of the things below, and it worked after last one:
- spammed "/cofh killall" both in the Nether and Overworld
- used "/opis" and Purged both in the Nether and Overworld
- toggled the Difficulty couple times from Peaceful to Normal both in the Nether and Overworld
I did all of the above as I had no issues with the Nether up until that baby Creeper ran into the Portal and crashed my game, so I was thinking he got "stuck" somewhere crashing my game each time the Nether is unloaded.
