[1.1 Royalty] High Stellarch death off-map gives -5 faction relations

[Flu007]

Circumstances: The "Royal Ascent" quest was available in the Quest tab, but not active. (Early game and I don't have the requirements yet.)

What happened: Double pop up: "High Stellarch died: The Exodus Empire" with the name of the new stellarch, and "Guest died: Petronas" informing me I have failed the quest Royal Ascent and relations with The Exodus Empire decreased by 5. (see attached screenshot)

I am running a few mods, but since this doesn't seem like a mod-related issue, I figured I'd post it here anyway. I can provide my modlist if that helps.

Savegames:

Saved seconds after the pop ups:

Hope this helps.

Quick addition, somehow I didn't think to look at this last night:

It seems this is only a wrong message that pops up, and the faction relations didn't actually change. (Still at 0.)

Which, I guess, turns this from a low priority bug into a very low priority one.
