I noticed a very weird glitch that I don't know enough about RPGMaker to figure out why it happens in the first place. It's pretty minor, but figured still noteworthy enough to mention, especially since it seems just so specific. I only just started playing the game today, and searching a few different phrases, I didn't find anything, so making a post. I assume it's tied to the "Retro-active fix for those who clicked a test-npc that made them lv99" part of the hotfix, since it only happens after installing the hotfix.
Basically, the first time entering Orchid Town after installing the hotfix, Alicia's "Xp to next level" gets reset to maximum. If you start a new save with the hotfix, this essentially means Alicia (but not Lily) will essentially immediately lose the 20 xp from the rat. I made a bunch of different saves in chapter 1 to test it, and whether the save was in town, or in a building and then I went to town, any xp above 0 (for that level) was removed the instant I set foot in town.
I did find a workaround for it though, at least if you're like me and just started playing, because it also appears to only do this the FIRST time you enter town after the hotfix is installed. If you run the game without the hotfix, kill the rat, get your license, then go do either Chicken Run or Retribution. Either of these quests, with the 20 from the tutorial rat, give exactly enough xp to be level 2. If you then install the hotfix, go into town again to register the 'first entry', and then it won't delete your xp later.
Is it huge? At the point I'm at, no. But I figure I'd still list it, in case it's also easily fixable.
