So I finally tracked down the last of the Sturgians and executed them (which royally ticked off my Vlandian allies because nobody likes a noble killer lol.) When I try to execute him, the game crashes (presumably to do with the death of a faction?) I've had the Steppe Bandits faction wiped out by the AI without it crashing, and I've eradicated factions in previous playthroughs (previous patches.) I have a save file from right after I captured him (I am always save scumming on this game for this exact reason because, Early Access.) On 3 attempts it crashed as soon as I clicked "Execute." I even loaded, moved around a bit to make sure the game wasn't just crashing for some other event in the game, and then saved again. Reloaded and executed him and the same thing happened, so it is definitely related to the execution (and likely the Sturgian faction being eliminated.)
