i can only run 32bit game on my pc, and here is lots of out of memory crash on 32bit game
Go into your stonehearth folder, and open the file user_settings.json.
In there locate this line:
"force_32_bit" : false,
Make sure it is set to false. If true, change back to false. This should make the game run again in 64 bit mode, which is the best mode.
