Couple of troublesome bugs.
Most of Veilbane's elemental sub-areas seem to be missing collision. Fire seems to function as it should regardless of some minor errors around the middle two fights, but Water's puzzles can be skipped, and Air's puzzles even seem to be shifted way off to the side for some reason. The puzzles themselves still work fine, though.
Earth, meanwhile, has a much bigger issue despite (heck, partly because of) its intact collision. While pushing the first boulder, I tried to click rather than using Z or Spacebar; this caused me to move away from and past it. I then started pushing the second boulder with Spacebar, which somehow pushed BOTH boulders, and when the first boulder ended up in the water, I couldn't push the second one anymore and was stuck in the minigame mode. I tried warping away with a Minor Teleportation Orb to escape it, but still couldn't move anywhere. Had to reset my save.
Also, I believe I managed to permanently miss Gobboe's last scene (unless I reload my save) for her first level of corruption (the "Standing Fuck" scene) and the Red Soul gained from that--maybe also the corruption gain? unsure--by having her give me the "coming for you tonight" note on the same night I left to corrupt Lucille. I got warped to her room, but then Lucille's scenes played out as normal. Now I have her Oathbreaker quest and can't see that last scene in Memories. Any way to fix this?
Edit: Furthermore, I tried "Queen Introduction" with Gobboe out of curiosity, and after saying she wouldn't be willing to do that yet it...worked, and started the Final Gambit quest. I'm not going to push it for now because I want to play the game in order, but...yeah. (Also, was I supposed to get a spell after Veilbane taught me something? Because...I didn't.)
