Stardew Valley 1.6 is live and all the farmers are out to play the best PC game once again. But before you can jump back in, you know and I know that you've got those romance mods installed. In order to work as intended, you've got to update SMAPI.
SMAPI 4.0 went live when Stardew Valley 1.6 did, and according to the mod loader's website, it improves performance and compatibility rewriting, adds per-mod-folder settings, and removes Error Handler (which is now integrated into the game itself).
