The aurora was partly fixed in 0.390, but not completely.

It looks like this now: https://youtu.be/367QC2pyZMY

Something is still broken.

Replication:

Untick/uncheck Enable under SKY

Use the console to set the time of day to night and set an aurora weather, eg

set gamehour to 1
fw 0010E1F2

Go outside and look up.

Wiggle the mouse around.

Thanks for your finding, it's conflicted with ProceduralSun, will fix asap.

Awesome! Thanks a lot.
