Jackbots being overhealed instantly?

It's a bug. I saw a slightly damaged jackbot, ran up to it and pull out my heal gun as a support, and -BAM!- instantly overhealed it.

Was this coming out of your base, on the way to the enemy's base, or in the enemy's base. I've seen jackbots make it all the way across the map without being overhealed and the instant they hit the enemy base, it's overhealed. Whether or not the support hit it quick before entering, I'm not sure, but it's pretty insane trying to knock down a Jackbot when it's overhealed and the Assassins can't tell a grapple from a hole in the ground.

...During overtime, 3 (or more) enemy JackBots were at my teams base, and ALL of them were overhealed. I was a Gunner, and managed to help destroy 2 of them before the 3rd did so much damage that the enemy team came in and destroyed our money ball. It was still fun, but also felt like a huge serving of BS.

A few times I have seen an attacking jackbot standing right next to their/our moneyball to only instantly get a full overheal out of thin air, sometimes that bug can really tip the scales of a match.

I have also never been able to overheal a jackbot myself, might test it out using healing + crits to see if it makes it any faster.
