Hi,
newest update details from Steam forum:

------------------------------------

"szept. 4., 13:13
Ninja update to Friday's release to fix a few problems that have come up.

Fixed hang if an artillery unit exists that has an engine but no crew.
Fixed crash if random factions ticked for a custom game on a map big enough to house all factions.
Fixed a significant bug in the scenario editor with agricultural tech not being saved for factions in the first era.
Fixed factions with no forces on settlements not being saved in scenario file.
Adding an edict in the scenario editor cancels edicts it normally cancels, and deleting an edict deletes edicts that depend on it.
Ctrl + G now toggles the grid in the scenario and map editors."
