I'm using Chrome and ran into the bug early in the game. It persisted through rebirths, so it was affecting all classes. Basically if I minimized the game for even a brief moment it would give offline progress when I reopened it. The offline progress was about 100,000 seconds worth. Might be the maximum amount if you have it capped at 1 day?
It only stopped when I refreshed the page.
