When inspecting a Colossus with lots of health, the window will show "2M Health" even when the health is 2.7M.
And to update this a bit - now with all the changes and having better gear, the DP and DCD have similar problems. You can get multiple million values in a lot of these screens, and you can't see an accurate damage/crit damage/DPS value as it will truncate the value to the million place.
I've added this to our bug tracker, thanks!
