It's been a while since I downloaded the game. My current version is 15.1. Would I lose my saves if I were to update? And how would I go about doing said update?
In the list of download files, pick "HH v0.15+ > v0.16.2 PC Patch (REQUIRES v0.15+)" and do what the read_me file says, It's super simple and you will keep all your saved progress
