Add crash-reports with sites like https://paste.ee/
It is an issue with Optifine
Combine OptiFine HD U I6 pre6 with Forge 47.1.43
If you want to keep on Forge 47.2.1, use Rubidium and Oculus as Optifine replacement
If there are further issues, add the new crash-report with the given site and link it here
You can try other builds of XaeroWorldMap
With FTB Chunks you should have a worldmap 🤔
MythicMounts? Replace it with this build
https://www.curseforge.com/minecraft/mc-mods/mythic-mounts/files/4095954
Remove Optifine
If you want to use Shaders, use Rubidium in connection with Oculus
If you want to keep on Optifine, remove Rubidium and use Forge 43.2.14
If there are still issues, add the new crash-report via
https://paste.ee/
Just post the paste.ee link here
Fixed it. I had time to spend 3 hours adding and testing all my mods by logic groups, each group one by one.
The rest of the problem was with several mods who were lacking dependencies not loaded by CurseForge, and some mods which were simply not working.
Thank you so much for your help, I can play now.
