Hello, I just downloaded the Replay Mod to start my new series.... on version 1.12.1. I have liteloader and forge for version 1.12.1.
When creating a new world it gets stuck in de loading screen.
Which version of Forge and the ReplayMod are you using? There used to be a bug in Forge which we included a dirty fix for in the RM. They have tried to fix it several times themselves and one of those fixes might be conflicting with the one in the RM.
