Re: world not showing up

Hi @Kaitlen18. This generally means that you've got a mod that needs updating or removing. Check Broken/Updated Mods for several that have recently been updated. If the lists there don't fix your issue, you may need to do a 50-50 of your Mods folder to find the culprit(s).

A 50-50 means organizing the files there into bite-size batches and testing one batch at a time. For each test, delete the file called localthumbcache, then put only that batch in Mods. If your game behaves as you expect, set that batch aside as "cleared" and delete localthumbcache again. If it doesn't behave as you expect, take out half the batch and see if you're closer to finding the culprit. Remember to delete localthumbcache each time. You'll find some 50-50 method tutorials online too. Once you isolate the file, you can go find out if there's an updated version.
