I am using Android, my regen percentage as recorded on my profile is -46%, been in the same faction, the bonus units are in place but my health regen, at least as it is written on the splash screen has lengthened from 13:30 to 16:55.
Not sure why, had an old self picture of bonuses, the percentage is the same - don't understand
Oh, yes, the time till the boss runs away is somehow increased to 2 hours and 2 minutes.
Another Gree success...
