Okay this is just plain bad
Using the fire in the slums picture for the Shark scenario. Now I just had the slum fire scenario come up in a Planet report prior to this so maybe the pictures aren't hard linked? They probably should be & if they are then this one needs to be fixed.

Something is definitely glitched - got the slum fire picture attached to to the Diablo Catalyst artifact for 3 in a row.

Okay 4 in a row

I saved the game between 3 & 4. I'll quit out to Steam screen and restart to see if that fixes issue.
That seems to have broken the loop - I'll leave it up to you to decide how it happened. Attached a saved game if that helps.
