Why is this happening? "Invulnerable" garrison boss

First of all, sorry about my poor english; ill try.

This match it has happened around 10 times, in 3 days.
We attack the main keep (garrison) of the enemy server (It only happens in the same server map, not the other or at our map). Then the boss is “invulnerable”; we just canT kill him, all the damage is denied.

if you see the screenshot below, it has the invulnerable buff. its impossible to us to take that fortress, making all our efforts a waste of time (and the enemy does not need to defend it)

As i said, it only happens in the same server map; we send tons of reports about this and sometimes it seems to be fixed; but when we lose it again, and we try to recapture, its usually bugged again.

before thinking that there is some type of exploit with this, i want to ask you if there is any mechanich making this happen; maybe its our fault. Or is it just a bug?
Why, or when, this boss can have that buff? its happening to you too?

Thank you!

If an orb is placed at a keep, that Lord will be determined (invulnerable) until the altar is destroyed. Destroying the altar should remove the determined state from the lord.

However we did discover a bug yesterday that could cause the lord to not drop his invulnerability in certain cases. Given how long it has been occurring for you, my guess is that keep was affected by the bug.

We have already fixed the cause of that particular issue on our development server and are testing it now. I’m hoping we’ll be able to get the fix pushed up to live next week, but we’ll need to make sure we are not causing additional issues first.
