that's a shame, I have no idea how it happened, but is a save file that is 8,000 kb normal for the game? guess i'll just have to pass on it then. Loved his earlier games, but thinking back to it, hasn't saving/loading issues being an issue with the games even with the RPG maker ones? Like I said in my post it could be use of skip, or that I saved in dialog, appart from that I haven't done anything which would cause saves to take 10+ mins to loadDarktoz made a poll recently, to see who got problems with running the game and who doesn't. And about 92% of his patreon supporters said they have no issues running it.
Like Aseratrix, I have 16gb ram and I also never had an issue with the game. And I can run it without the game slowing down significantly after 50 days or so.
I doubt he will do much fixing unless you can tell him a specific solution that does not affect his playerbase who can run this game without issues.
