Except that it happened when there were ZERO provokers present at some of the invasions (often, I'm one of two bards on LA there, and in that case the other wasn't around, and I was on one of my chiv users to get a Titan in for rewards - an ABC, a macer/smith, or a melee T-hunter). The only person it was happening as the displaying target for EoO was NOT a bard, but a character using a trained lesser hiryu with Chivalry as its magic skill - and it only started for ALL THREE of my characters mentioned after the Hiryu started spamming HL - in at least 2 cases where I was the only one fighting the general before the Hiryu came in, and there was nothing in the area to provo on it in the first place. And, strangely, none of the other melee character players on LA are reporting this happening when my Tamer/Bard is provoing masses of 3-8 things all onto each other - though that might be a factor of rarely seeing non-tamers in the field in this event.
It could very well be two separate bugs with similar end effects. I mentioned both possible scenarios to Kyronix at the party.
