Can't access any singleplayer world #44

Closed isuewo closed 3 years ago

isuewo commented 3 years ago

I have no idea what went wrong but I was able to play singleplayer until today. The only thing I did was teleporting back from the end into the overworld by using /execute in minecraft:overworld run tp @s 0 100 0. I remember it stating something like command couldn't be executed in chat but it did in fact teleport me back. The only problem was that nothing was rendering and I couldn't interact with my world. I then decided to close the world and join back in but then got greeted with a message saying: Invalid player data and got shown the multiplayer server selection screen. I tried everything to get back into my world and I can only do that by removing krypton. The weird thing is that I now also can't access any other world because I also get show the same message. Multiplayer is completely fine though and I'm also using the latest build of krypton if that somehow matters.

Here is a log of what's happening every time I try to access a singleplayer world: 2021-08-05-7.log The only thing wrong there I can see is this one uuid that causes an ambiguity between arguments in line 46-50. It's also not the uuid of me so I don't know what's going on and it's also the same for any world I want to join.

Not actually fixed, that is a workaround disabling the offending mixin. Reopening.

Fixed. I didn't realize ServerWorld was shared between the client and the server, which meant a required mixin wasn't getting applied. On top of that, Mojang apparently employs the Pokemon Exception Catching pattern as well, which made this issue hard to diagnose.
