As someone who was hired only months ago by a high tech company doing software work with a massive codebase, I absolutely understand how insanely daunting it is to try to navigate code you didn't write or extensively work with before. Complicated bug fixes can take days to weeks (or even months) by experienced employees, and this is in a paid environment, 8-9 hour workdays. When I'm off work, I only have a few waking hours at best each day to distribute between everything else in my life. Flip this around, where folks only have a few hours at best outside of work and staying alive to possibly allocate to this passion project, and it's perfectly reasonable that this monumental process takes time.
