So this has happened to me twice now and I have no idea what is going on or how to fix it but whenever I download a mod where you have to click the config.json file... (example: http://www.nexusmods.com/stardewvalley/mods/451/?) ... and and edit the number it always works... for a single day then just stops out of no where. I have tried redownloading and resaving the file but nothing works so far. Any idea what is happening?
Hmmm, I don't have any experience with that particular mod, but that kind of behavior really shouldn't happen without you having a part in it. I use timespeed and the settings i adjust always hold. Are you doing anything else with the files? You really haven't given much to work with in your report.
log please, I need information available in the log so I can help you See http://stardewvalleywiki.com/Modding:Player_FAQs#SMAPI_log on where to find the log.
