More crashes, when bonus tile's selected, whether I have the tech's irrelevant.  So is whether it's under zone of influence.  Very often now, the game crashes from such selection.

In this save, game crashes after casting 'wither' on enemy nearby my sovereign (to the east of map), then selecting the tile underneath him.  I usually go through several actions beforehand, though.

Also, here's a save a few moves after the above save, with a bug where enemies with 0 hp are still alive after I killed the army near sovereign with the strategic 'Wither' and then tactical 'wither' that reduced their constitution to zero. (6 death shards ftw).  Game didn't crash this time, despite crashes each time before when crystral crag under sovereign was selected.
