[A16] Raid Fails to Spawn, Citing Out of Bounds

[maarx1337]

Got a red-letter notification for a Raid, but the enemies entirely failed to spawn.

Simultaneously, got these errors in console:

Tried to get valid region out of bounds at (-1000, -1000, -1000)
Tried to spawn Matthias out of bounds at (-1000, -1000, -1000).
Could not find siege spot from (-1000, -1000, -1000), using (-1000, -1000, -1000)

Of note, the red-letter notification did NOT indicate "Siege", it was just normal "Raid" (they will prepare for a while, then attack).

Sorry, don't know how to replicate this one, but figured I'd report it anyway.

Couple minutes later I got spammed repeatedly with ...

Pirates from [Faction] are beginning their assault!

... and the below error got spammed repeatedly into console.

Once it started to happen, it seems there is no way to fix it. Even re-Save / re-Load continues to spam the error. I had to roll back to an earlier save before the raid failed to spawn.

It happened again on my next raid, too, actually.

Since this one wasn't "prepare for a while, then attack" I figured I would wait it out to see what happened. After a while, I got:

Raiders from [Faction] are giving up and are leaving.

No error spam, though, which was nice.

[Illusion Distort]

It seems the raid is trying to spawn way out of the map... Can i have the full changelog please?
Might contain important information about how this came to be.

Happened again.

With that many mods it's possible that it's caused by one of them. We'll see if anyone else reports similar issues in A17. Thanks for reporting anyway.
