Firstly, great game, well done!
However I've encountered a problem reloading my saved game. I played for a couple of hours yesterday and almost completed the mine, saving multiple times as I went. However when I try and "Load The Last Game" today nothing happens when I push the button.
Looking at log.txt I see the following error message:
0.000000: error on 'load': can't find the game slot '-1'. => line: 20690, file: main.cpp
I had created about 6 saves in total and deleted 2 or 3 of them at one point to tidy up - I'm wondering if the deletion has caused an issue with the game slot counter possibly?
I noticed the save.dat file is xml - is there possibly a way I can edit this to point back to the correct save slot?
