Open Client freezes when switching singleplayer worlds

[Mikemk]

Summary of the problem Client freezes when switching singleplayer worlds

Pack Version 1.0.0

What is the bug? When switching between my test and play worlds, the client freezes up, requiring I force close in task manager and restart. I believe it happens any time the world being loaded isn't the first world loaded that session.

Mod & Version Client bug, no mod

Is it repeatable? yes, frustratingly

Will need your full log, not able to reproduce.

I'm posting the full log. I returned to the main menu at:
[22:12:26] [Server thread/INFO]: Saving and pausing game...
And started the next world at:
[22:12:32] [Server thread/INFO]: Starting integrated minecraft server version 1.12.2

Also, it occurs regardless of whether I enter a different world or the same world.

The log was too big for a single pastebin, so I had to split it. Both above events are in the second part.

perhaps related: the exact same issue is known in other packs too, all the mods 3 for example: For me there is no way to exit a world and start the same or different world from the menu again without having to restart the client in single player. I personally think this to be a forge problem. https://github.com/AllTheMods/ATM-3/issues/79.

I cant reproduce this on two different PCs but will get this reported to forge devs. Thanks for the expanded info.

I am also experiencing this now when trying to reopen my SP world after getting the SimpleStorage glass in crafting recipe "payload" issue.
Let me know if I can assist with debug logging.

i have to add: After the payload issue i can reconnect to the world (only then) BUT in that case the chuncloaded chuncs (via pressing "E", then in the upper left corner of the screen) are not chuncloaded any more and i cannot Re-chnunload them until i close the client and re-open the world. Since this i tend to restart the whole client after the payload issue.
