Playing shade experiencing-
Sticking weapon switch especially with Javelin.
Enemies randomly seeing and targeting whilst invisible, some stormies 180 and instakill with an overhead then suddenly revert to what they were actually targeting.
Phantom hits with daggers held in block.
Packmasters and storm verm in breeding on the spot- duplicating (or having 2 spawn in the exact spot doing the exact same animation inside the same slot.
Balls of patrols are appearing out of nowhere- especially on War Camp toward the beginning drop.
All this happens on Cata and unaffected by mods.
Hope this helps.
