AI turn freeze fix — Zodiac Legion Steam update #1399962

Greetings commanders, Unfortunately, a bug made it into the AI code shortly before the latest demo update, and I got sidetracked by family matters, so I could not fix it in time. I have altered AI calculations, but in doing so, I had to modify the way it approached door opening. For the moment, I had to prevent most AI groups from opening doors, otherwise they will all converge to the starting location (or latest known position) of your team. So the AI should be much less agressive for now. In the next patch (if I didn't break something else), I will make them go back to opening doors (or not) depending on their mission and the alarm level. The AI group missions will be either to search for your party, to reinforce a friendly party, to patrol the level, to guard a location, or to take an objective. Thank you for your patience and your support.
