Enemy spawn count is low, spawn rate is slow/low, invisible wall, and codex scanners don't equip.

Just now I had a lith relic exterminate mission where on loading, everyone lagged on load-in. Enemy spawn count was 40 total, normal enemies didn't spawn on a grineer earth tileset, and a teammate and I experienced an invisible wall blocking us from moving. Additionally, only enemies that spawned were the corrupted variants that come out of the portals that drop the catalyst for relics. I have a few screenshots taken with F6 button.  Oh! I and another teammate tried to scan a frame fighter character data thing, and codex scanners wouldn't equip. Below is an imgur album with the pictures, and I have also submitted a ticket in zendesk. (And thanks for taking time out of deving fortuna for replying/fixing this)

Enemy spawn rates seem to be too low in many missions since the update. Exspecially annoying during excavations. Even with Nekros. :(
