Plains of Eidolon massive rendering issue

[Sjana]

This bug is a little strange, so I'm not sure how easy it is to replicate.

Basically, when I enter one of those Flying thingies that the Grineer use, sometimes it bugs out and I am able to pass through the Blue wall.
When I passed through it near the exit, an entire different map loaded in all at once and started dropping my frames massively. It hung at 40 for a bit with huge freezes until it bunked below 1 fps before crashing. I sent a crash report but I don't know if it will tell you what happened, so I decided to make a post. I wasn't Streaming at the time so I have no recording.

The map that loaded in was a completely different map from Plains of Eidolon itself. I hope this helps you in determining what caused this very strange bug.
I tried to take screenshots, but the game was lagging too badly for it to even attempt to screenshot.

Yours,
