Good catch on Lani's xp. Looks like I neglected to reset her next level requirements at the time of rewind, just as mentioned. I've corrected it for the next version release.
As for the titles, those are legacy variables, just left in the code to avoid breaking old save files. I've since moved the titles into a better system, but I'm wary of cleaning up some of the legacy stuff too soon after moving it to obsolescence. I know a lot of people will play a game and then come back to it six months later to see what's been added, and I want those people to be able to come in with their saved games intact if they were so inclined. I think that once Covid is over and I have my development time back, I'll spend a dozen hours or so just cleaning up and removing legacy code.
