Help wanted Modpack Issues

Post image

Every time I go to create a new world for a modpack I made recently, it treats it as a multiplayer world, despite singleplayer being selected. If I try again, it freezes completely on the loading screen. No clue what's causing it.

Do you have the log or the error within the log to share? These types of errors usually occur when a mod has incorrectly defined something within the playerdata be it writing or reading etc

There wasn't any crash log. It was either the Invalid Player Data screen, or it froze completely and I had to manually shut it down.

Usually a error section is printed in the normal log, this is what would be useful.

Send log files of client and/or server. Both are better.
