@JinbailiK Did the game crash? or did you just get stuck? If it's the latter, it's going to be fixed in the next patch. If you do happen to get stuck like that again, press right shift + Del + R
@baileykrebs You won't have to restart, you can keep playing on your existing saves. Some of the new stuff in 1.5 is based on starting a new save (e.g. the advanced game options) but most isn't
@paulonaytor There were issues with certain mods, when 1.5 first came out, that have since been fixed. Have you tried updating to the latest version of SMAPI and then reloading your game with that?
