Oh I do apologize, didn't know your name was in the credits! WIll have to have a look for you in the credits, your name there is picklebird?
And by the way that you were communicating I just figured you were some other random gamer chiming in on "what they thnk they know".
As an example:
Player is directly strcuk with rooting agent/Goop. Player who is suppose to be object enclosed"rooted" moves from left to right, and is able to jump.
In another example of where I've seen possible bug abuse is someone noticing that they will not die as a engineer if they are interacting with a turret, suddendly stop, jump on and directly back off the jackhammer, thus suddenly avoiding death. Also while this happens the player seems to not be able to be attacked. I've only seen this working against chompers, and have done it to chompers coming after me!
Let' see how else have I noticed people taking advantage of gaming flaws related to the chomper... Oh I will get back to you as I am in a game currently, and will switch to other side after this round to test my other thoughts..
