Hello!

 

I couldn't find a place to report about the LaunchWrapper problem so I'm reporting it here.

It might be fixed here:

https://github.com/Mojang/LegacyLauncher/commit/347fff7200f4acbe189b2a3710a46a6bb8032c9d

 

But there's sadly no LaunchWrapper 1.10 it seems.

Try without PitchFix

It should work fine as yes java 8 changed this section of code slightly, but it should still be backwards compatible.

 

I do Forge for free, however the servers to run it arn't free, so anything is appreciated.

Thanks, I will test out some of the development builds.

However, as the agreement you agree to when downloading early access states, shit may break :P

The official releases of Java8 all work fine with Forge/LauncherWrapper.

I do Forge for free, however the servers to run it arn't free, so anything is appreciated.

      regarding Invalid player data

      By RRS · Posted

      My apologies, it's a Postscript. I was able to play for an extended period of time right after generating the world without any problems. If I close it and reopen it, I get that message at random. Once it appears, I have to modify the Level.dat to open it.

      regarding Invalid player data

      By RRS · Posted

      Hello.  regarding Invalid player data.  First of all, my English is not good, so there might be mistakes. I am using Minecraft 1.20.1 forge 47.3.22 CurseForge and have over 250 mods in my modpack.　Single-player. I can play the game after generating the world (about 5 hours) and restarting it, but there is no set timing and one day it suddenly shows ''Invalid player data''. Restarted the game several times after that, but the same message appears. Fix the level.dat file and play for a few hours, but the next day when I try to open the world I get the ''Invalid player data'' message again. Can open other worlds, but after some progress in the other worlds, the same message appears and I can't start them. Is there something wrong with the mod configuration? I would be very grateful if you could tell me how to solve this problem. ◉ErrorCode https://mclo.gs/4gcfPbY   ◉ModList AdvancementPlaques-forge-1.6.9.jar AI-Improvements-1.20-0.5.2.jar
