Why does SMAPI 2.0 break mods? SMAPI 2.0 lets mods do much more, but it no longer supports old deprecated APIs. Any mods which still have deprecation warnings won't work in SMAPI 2.0. How do I update my mods? Follow the instructions at updating mods for SMAPI 2.0. If a mod is still broken, post a message in this thread and I'll help. Make sure to attach your SMAPI log after trying the mod. What do modders need to do? If your mods are broken, see for mod developers.
