(Switch) I fixed the mine bug! Step by step instructions.
While I no longer own the game myself, I have a friend who still does. I tested a theory about a potential memory leak/memory issue in the code, and it appears (so far) that I have solved the mine s text box bug. These are the steps that fixed it.
you need to move sunhaven from your SD card to your hard drive. To do this: - go into system settings - go to data management - go to move between system/micro SD - move sunhaven from the SD card to the system
this next step is NOT optional. It may seem odd/strange. But it will give a "buffer" area for potential overflow data to run into. You need to create 8gb worth of space on your system if you don't have it. You can either delete games from your system memory to do this, or shuffle things over to your SD card. IT HAS TO BE ON SYSTEM MEMORY. IT CAN NOT BE THE SD CARD.
after this is done, load sun haven and go into the mines. Please post if it works/fails. So far it's had 3 successes. I'm hoping it at least gives everyone a temporary work around till they eventually realize where the memory leak is in the code.
