I tried that. fresh install without cahngeing anything but it still did it. When the game loads and a farm needs cropping or planting, it works fine but if i leave it running for 2 hours and it reloads or i refresh it myself and nothing needs doing it breaks.
Also on my second farm account i have no crop fields and it never breaks on that. im not sure what it is
FIXED --- not really a fix but for anyone experiencing this make sure your fields are cleared of weeds and such.
