So I started a new game upon the latest unstable release, made my way through the new town progression and was having a great time when I hit my inventory limit, and then shortly after the entire game started slowing down.
Investigating, I found that the various new town buff progression things such as the Banner of Cunning and the Stump Hearth, combined with my own extreme gold acquiring ways had resulted in a gold pile so big my hearthlings couldn’t shift it all.
It had amassed to over 4 million gold.
Buying every item from every merchant and never selling a thing couldn’t hope to deplete it enough. My hearthlings stopped farming as the inventory limit wasn’t just hit, it was disintegrated. They had nowhere to store food. They slowly starved as they frantically and futilely tried shifting my endlessly growing piles of coins into storage. The entire game slowed to the point of unplayability due to the amount of gold lying around on the ground being rendered. I eventually had to force quit the entire game because of my endless unending wealth.
As game breakers go, this one was pretty darn awesome.
