I'm unable to reproduce the first turn crash on the 1936 map, a log would help.
On the 1940 map it was caused by a Swedish infantry going into a lake during first turn (I don't know why it make the game crash while other AI units goes in sea on first turn already without causing crash... so I've just moved a bit the starting position of the unit...)
