Repeatable crash when you set those ancient bombard units (forget the name) to auto-promote if they are glowing. Might have something to do with them having no promotions available. This has been around for ages just never remembered to report it.
On a side note, im being attacked on all sides by pesky thieves and rogues which is nice
edit: That reminds me with viewports on and when rogues attack me or pillage I can't tell where it is occurring. If I click on the message it should centre the screen to where it occurred shouldn't it? Sometimes When enemies have been spotted off screen or barbs pillage, I am unable to re-centre in this instance also (sometimes anyway).
I probably disabled message-click centering when off-viewport accidentally. If you have a convenient save game that will show it up on end turn please post it together with details of your viewports settings and I'll look into it.
