I was playing on ironman difficulty about a week. Today when I quit the game (alt + F4), the game crashed and deleted my only savegame
I found the savegame directory. There is the only savegame and the file size is zero bytes.
%HOMEPATH%\Documents\Xenonauts\AutosaveIM2015-06-13_09.57.27.sav
It would be great if the game made file backups before start writing them.
Some other issues:
* Stun baton's pop-up tooltip says that it takes 20 TU to attack. However in practice it takes 20% TU.
* Right after completing the land mission and founding a couple of new artefacts, there are some new researches in the base research screen with empty or strange descriptions.
* It seems that aircraft weapon damage is incorrect in xenopedia.
* If you throw a smoke grenade and end the turn, some smoke fields disappear. If you reload the auto-saved game after this, smoke fields reappear.
