Hello, I am having an issue with my worlds, right now I have around 25 mods loaded, but when I downloaded a new mod minecraft prevented me from loading my worlds. I can still create new worlds so I don't think the problem is a conflict between mods. I have a big project that I don't want to lose but I don't know what to do, can someone help ?
I'm having the same problem, I have around 25 mods loaded. I downloaded one more and then all my worlds showed me this message when I tryed to load them, creating new worlds works though. I realy don't know how to fix this.
