Posted July 30, 20223 yr Hello, I've switched from a working world in 1.18.1 to 1.18.2 Forge I've gone through and picked out the 1.18.2 versions of each mod I use in my custom pack. Though when I go to load the world I get an error "Errors in currently selected datapacks prevented the world from loading. You can either try to load it with only the vanilla data pack ("safe mode") or go back to the title screen to manually fix it" clicking safe mode does nothing. This error also occurs in previously made vanilla only worlds. I'm not sure what to do I put a ton of hours into my previous world, the only reason I updated in the first place was to use the new create mod, this is pretty much my last ditch effort before giving up. Here is a link to the Zip File Containing Mods and Debug Log. I'd like to save my world if possible. Thank you, Queen

While they have a way of updating vanilla structures, it can't fix modded structures - before 1.18.2 there was no standard format for this data. The only thing I can suggest is to talk the mod authors for the world gen mods that you have. They may know a way to fix the data? Boilerplate: If you don't post your logs/debug.log we can't help you. For curseforge you need to enable the forge debug.log in its minecraft settings. You should also post your crash report if you have one. If there is no error in the log file and you don't have a crash report then post the launcher_log.txt from the minecraft folder. Again for curseforge this will be in your curseforge/minecraft/Install Large files should be posted to a file sharing site like https://gist.github.com You should also read the support forum sticky post.

I'm not entirely sure which mods Generate structures :(
July 31, 20223 yr Use the /locate command it will list all structures in the autocompletion. The part before the : is the mod name.
