installed version 1.2 and started a new game, the old sovereign lost his head, so I created a new one, have played and beaten the game (with no more than the 1.19n bugs)
started a new game, the custom sovereign lost his head again, this time I didn't create a new one, the sovereign didn't have any weapon or armor, and a bunch of headless units appeared near the pioneer
notice the map borders, the game seems to use the dimension of the preceding map, at the beginning of the last game the borders of the map of the preceding game were visible, where you can see colored pixels

as for other texture bugs, this one disappears if you exit and start the game again
