Dear Minecraft-Forge Team:
I came here to post my issues because I all my research of this issue, were unsuccessful.
I tried to play the FTB 1.14-Unstable pack and I was unable to launch it.
After that I tried to disable certain mods which are known for causing issues, while I discovered that mod-devs blame in some cases each other with no real solution.
I want to apologize for any inconvenience I might cause.
In general I have 2 major issues:
1) Issue: ColorHandler
People claimed that other mods messing something up, which causes this. I notice that mods in general which seem to use a method to colorize single sprites ingame to make a dynamic map, have this issue.
I was unable to find any mod which causes this, so I tried different Forge-Versions. Mystical Agriculture is a pretty good example, because it or at least the LIBRARY uses a pretty high forge Version. None of them worked.
this might need some further investigation
Crash Report.
2) Issue: Night Config I/O Exception: Writing
This is the main Issue why I came here. The issue appears to be random because every time the game freezes and crashes on a different config, general it is only by mods with the new config-system.
I my suspicion were access-problems and rights, but I didn't found any issues with that.
I was searching for a solution and most people have only trouble with the "not enough data" issue, which is definitely not the same as I have.
But I tried to delete the fml.toml and forge-client.toml. It didn't work.
Crash Report.
I have to mention, that the config the Exception is thrown seem to be random. Deleting the folder and recreate proofs that.
