I've spotted a different one (different name, but I guess they change their name all the time, so that the naming doesn't make sense). Yesterday during the mystery portal event, also on the European server. He played a plant but looked like a zombie. It was obvious when he (I just say "he", but it can also be she or it) played some sort of hovergoat, smaller than the usual with a different look, and used goat's ability to "help" teammates (don't know the English name for it; it's the one when the arrows show and the target is faster etc.). Thus people saw that something was amiss. But mostly he/she posed as normal soldier or scientist, whilst being on the plant team. Most plants were busy trying to shoot him, and he just liked the confusion. Only once he had a small amount of vanquishes (the team lost anyway), but that's maybe because people would have known too fast what's going on. - What confused me about this special player yesterday: He even has a rank of 9, so he's obviously been around for some time. 🤒
I really wonder how such a thing is possible. Fortunately he didn't stay long in our mystery portal team, or maybe was kicked out because of his re-spawning ever so often. But he did cause a lot of confusion. 👿
I think in GG rounds it's more annoying, because long games can be completely ruined. Or if he would be part of a boss hunt in the mystery portal.
