Hi! I'm playing on Minecraft Forge 1.12.2-14.23.2.2611 and I'm having an issue at loading my vanilla world that was not generated on forge. I have used Forge in this file months ago, but it doesn't work now. The world gets stucked at the Building terrain screen. In the minecraft log, it appears the following:
This is the FML log https://pastebin.com/5itLjiUT
The mods loaded in my mods folder are BBOutline Reloaded, Lunatrius Core, Schematica and Tickrate Changer, I don't think any of these affect vanilla.
Hope you can find my problem, thanks!
Edit: the world works fine in 1.12 Vanilla / Optifine
