Just got back to a solo project I hadn't touched in 5 months due to having other priorities. The whole thing is probably less than 1k LOC split over a half-dozen files and I'm not sure whether I should be angry at my past self for leaving the most recent part untested and insanely bug-ridden, taking almost an hour a fix, or be happy that past me organized and documented everything well enough for it to only take almost an hour to fix.
