Crashing mid-late Summer

No idea what is causing this. Didn't feel like I'm approaching any sort of landmark, etc. But I have tried not doing anything and progress to the next day and still crashed out.

 

Updated SMAPI to the latest version. Not sure if the same error. But still can't get past 20th of Summer without crashing out on saving.

 

(Parsed log.)

Does this still happen if you reset your content files? If so, what if you temporarily remove all the mods (but still run through SMAPI)?

 

Many tries later.
Did not reset content files BUT:

Went to updated Animal Husbandry and Lookup Anything that came around relatively recently and that seems to have fixed it. Strange though that SMAPI was the one that gave the error and not those mods. Or was it just blind luck? ;

 

The actual error is from the game code, probably due to something Animal Husbandry was doing. It's shown under SMAPI because it caught the error and logged it.
