Hello, Bit of an odd question. I just started a dedicated server for me and my friend. As recommended on the wiki i created a singleplayer world with custom settings (20 day per month). But i didn't change any of the food / hunger / spoil speed settings and am now seeing that this might become an issue. Can i, after 7 in game days change the server settings (back to 9 day per month) in the serverconfig.json without any issue or should i restart from the beginning? Thanks in advance for any answer.
