Alright, so I'm not getting a crash in any part of your farm. I tried both Luma and NTR, neither gave me any problems. I did notice you have mushroom logs in your farm, which is most likely the cause of the crash. I've had multiple reports of crashes stopping after the logs have been removed.Sorry for the delay, had some stuff to finish. Here's the saves. The 18th of Spring is the one that messes up.
I have no idea why I don't experience the crashes myself, but I have no way of figuring out a fix on my own without being able to replicate the problem. I do think you should try my earlier suggestion of combining TLE into the v1.1 update cia. I can't promise it'll fix the problem, but it's worth a shot if you want to use all your items.
