Folks, I'm seriously trying here... and thought last night this was going to be a breeze. I started with the Steam version which, due to the dev team building the new update on RenPy 8 (versus the original RenPy 7) there were some minor rollbacks upon old save loads but nothing way too dramatic, only a low percentage of failures as expected. BUT the non-Steam version is something completely different and I've spent 5 or 6 hours last night unitl ~0300 hours in the morning, got a few hours nap and now another 3 hours or so.... and it's driving me completely mad.
I'm having hell with the non-Steam version throwing exception error after loading the save then right-clicking or hitting Esc to reach the Navigation menu system. New playthroughs are NOT effected but folks want to be able to load their old saves, I get it. So, I'm working hard on this but this has been a massive delay... just massive. Basically 10hrs of getting the initial porting done (everything up to the new content) then code cock-blocked.
I'll keep you posted but I'm quite frustrated atm. It's really pissing me off as I should know how to handle but I've not seen this type of behavior before, even with other VN's that have bumped RenPy versions (which is always a headache if I'm being honest).
