Hey, thanks for the kind words and the bug reports :) I'm glad you enjoyed the Kana event!
Onto the technical issues:
1. The "#DEVCODE" thing is utterly inexplicable. It only appears if you load an old save that's in the Manor bedroom, and only once. Refresh the screen (my changing locations or clicking a dialogue option that sends you back to your room) and it's gone forever. There's nothing in the code to explain this, and I have zero idea why it's occurring. My current plan is to just leave it alone and see if it goes away of its own accord, haha.
2. I added new Leads to the Kana questline and it borked some of the older code I'd put in place to prevent duplication bugs. It should be fixed for 0.21.7 but let me know if it crops up again! Questlines involving Lyx always seem to get messed up... I wonder why?
3. 0.21.7 or 0.21.8 will have an option in the preferences menu to set a personal speed for the timer (or make it instantaneous). There will also be a proper "clock" UI put in, probably in 0.21.8, so people with the top bar minimized won't feel like they're trapped on a black screen while the clock ticks up. I wish I'd had time to refine everything before release, but I'd already delayed too many times and I wanted to get the thing out!
Again, thanks for the kind words and for taking the time to write up a detailed report! :)
