Hope that screenshot-steam-thing works for you…
Edit: Sorry, I totally forgot to mention how it occoured!!! Sorry!
Not reproducable for now, I will try again this afternoon.
How it occoured:
I was ignoring the goblin king … and when I then clicked it, 3 or 4 caravan messages and traders rushed one after another, when selling/buying stuff this error pops up.
Seems to me as if the message system, when the active one is ignored and a not-automatically disappearing one, is queued one after another?
Edit2: I mixed up my errors, because they came simultaniously. Sry
