avr_gdb_init listening on port 1234

Address 0x18c6 seems to be indeed outside the RAM address space. This could be a bug in the game that shows up here because the hardware ignored the out of bounds write or it could be something else.

avr_gdb_init listening on port 1234

Attaching GDB and debugging where in the game this occurs may shed some light on the issue.
