Erm.... so I'm not quite sure what happened... but now I'm not getting any more souls. My 'total power generated' also seems to have reset... I'm not 100% sure, but I think i might have accidentally clicked 'reset' twice in a row just before it happened.
The upgrade menu is getting.... kind of hard to navigate with so many upgrades. Could you maybe change it so that there is one button for each kind of earner, and it switches to the next upgrade once you buy one? :)
 "Idle Necromancer"){kind=icon}
 "AdVenture Capitalist"){kind=icon}
That's a great suggestion! We'll see what we can do :)
