Hello,
Sorry to hear that, I set the gold to 5000 again, and fixed a possible bug causing this negative value.
I loaded your farm to do this, and I noticed you had some big dragons in your chambers, like boss size, does this happen for you too? boss dragons should only exists in your dungeon.
I also couldn't load your dungeon, did you not rebuild it yet?
This info would mean a lot to me so I can make the game better :)
Have fun playing.
