Thanks for the reply! Reading comments on there made me do a little research (mostly on Reddit, admittedly), and it seems like even the Astoria and Gangsters in Love official releases are only up to season 4 for all of the different routes. Had I known that, I probably wouldn't have bought them for 30 dollars apiece. I'm hoping when they release Love & Legends that they release it with all of the seasons for all the routes, and not just the first 4 as well. It'd really suck for your remix to get removed and then have them not fully release it for sale on Steam or wherever else. (I don't mind paying if we're actually getting all of it, y'know?) :(
Either way, I understand you'd probably need to remove it so that they won't think to pursue any legal action or whatever.
