You're right, I've experience this in countless missions. It's a disaster and even more when people have low specs pcs and try open worlds. To remind the Devs about some serious issues within their game: Khora's Whiplash ability not functioning correctly with the line of sight "update", people not able to attack nor use abilities in open worlds (this one I've solved it with the use of the K-drive / Archwing vehicles, still is obnoxious when it happends), SP kuva survival acolites not spawning when the eximus with the catalysts spawns (please, please fix this ffs). Thanks DE Steve and the devs
