Trying to figure out what is causing the units to lock up... We had this problem before where Arduventure took up too much ram and overwrites an address in RAM that is used to indicate a software reset.
But now we are using the latest bootloader on the Arduboy which moves the position in ram way out to the end, so this shouldn't occur.
I'm pretty sure I remember testing this, is it possible these are being compiled with older versions of arduino?
@MLXXXp any suggestions? are you able to test this?
