Just hit a bug (playing the browser version); had Auto-Forge on in the Realms tab, time warp at 20x. Switched to a different tab for a couple seconds (enough to earn like 20 Null Essence, so not long) and when I came back, I was no longer gaining Pristine Light, because I'm somehow at -2.6 million Quintessence. Considering I'm only making about 1.5k/sec at normal speed, that's a _pretty big_ deficit out of nowhere!
