I got off of SevTech Ages Of The Sky, the next day, I got on to keep playing, but it seems like my world is now in age 1? my Advancemnets say I'm in age 4. I have progressed up to age 4, but now I can't do anything to progress. I have tried restarting my game, and that didn't work, and when I type in any command, it says, "An unknown error occurred while attempting to perform this command. Here are my logs from before the issue and after the issue.
