I can't read the magazine on my current save, she keeps saying "i'm tired of reading this journal..." an it doesn't allow me to progress in the police event. I tried looping back to day 1, with obscure novel or matriarch flame, buying the magazine again, but same result. I guess you could fix this by forcing the variable 441 to a number "<10" and switch 202 to "0" when Rinko says she's not ready for this job yet. This would allow to read the magazine again and set the switch 779 police job unlock to "1" in common event 305.
Looking at it with a save editor, the cause seems to be that i've reach 10 on var 441. Both before and after looping. So you might just want to touch the variable. I'll edit it to be able to proceed with the event.
I also get error message when trying to access the syndicate, both on the world map or while entering the appartement in rinko's condo, saying .json of corresponding maps are missing. I've tried downloading both from mediafire and google drive, but the version is the same. Is this to keep the syndicate for patreons, or just missing files ?
Edit : Changing the variable down to 9 worked, also when allowed to go beyond the counter in police station, you can go out of bonds on top left corner, every tiles left to the shelves.
