Map waypoint not very helpful

[NinjaZeku]

It's happened to me quite a few times that, upon spawning late into a mission,
it wasn't clear where to go because the map basically told me to run into a wall or dead end.

(I spawned underneath that thing in front of me there, BTW, which further helped in being disorienting.)

Okay so, now that I'm standing here, where am I supposed to go?

The map tells me to go pretty much straight ahead (and then down afterwards, I guess).
Except nope, that leads to an unlit closed door.
I'm actually supposed to use the path to the right. With zero indication to do so.

On another occasion, I spawned in a long corridor in the Void,
with the map directions being at a ~90 degrees angle to the length of the tile.
Great, so which of the two exits am I supposed to take?

(And no, the large map wasn't any different.)

I don't really remember if this began with the Waypoint "upgrade" or not,
either way, things could be better and I'd seriously appreciate someone looking into this.
