Look's like that you can hire only one time 12 soldiers, else when you hire soldiers second time, previously hired soldiers can just removed from both "personal"&"soldiers" screens but they are still present in "assignment" window of "soldiers" screen and on "aircraft" screen. It does not depend from base you hire soldiers. Also you can start training only for 11 rookie soldiers - the training button for 12th soldier simply not highlighted and could not pressed by mouse button instead this the "not assigned/chinook01" menu appeared.

I have a same problem: When you start crash-site mission from geoscape all Ok (for both type of aliens). But if you try to load autosave or a game saved during the mission then you had invisible aliens, support troops and civilians. When you manage to kill some of these "invisible" alien -> CTD

Same problem with duplicated soldiers. Look's like it take place from October 1st. As I tried to understood the conditions: 1. If you have not enough money to pay monthly wages&costs then you will have some warning message and duplicated soldiers on base (bases). It happens even if monthly income enough to cover your monthly expenses. 2. You have enough money on you account to pay monthly wages&costs. No warning message appeared. All looks Ok but when you try to load any savegame from October it cause CTD.
