I have attached the tests I have done.
Don't know what happened but seems the game is crashing less frequently now. Maybe because of seasons?
The Cork bobber +
Seafoam Pudding combo was a guaranteed crash, but not anymore.
This is just a feeling, I haven't really paid attention to it.
It feels like the more harvesting I do on my farm before fishing the faster it crashes. This could also just be a coincidence.
When my game crashes it freezes for 1-2sec. then closes.
I did try "Right SHIFT + DEL + R" but that didn't work.
More info of my farm:
I have done Qi's 100% perfection.
I'm on 25th spring year 7.
If I continue to fish I will take notes of it, but I probably won't focus on that. I'm getting pretty tired of fishing.
If I find any new info or do more tests I will update you, but it might be a while.
