Since then the problem was made clear! Everytime I, and others, press the CTRL key to select multiple units during battle, the game freezes and the player is forced to ctrl-alt-delete and terminate the program because it won't respond.
Now the CTRL key is undoubtably the cause of the freezing, the problem is that even since March there has been no single fix/solution to this insanely annoying bug, I've scoured as many threads on the issue that I could find, but none of them have ever had any sort of solution, they'll have pages of replies from people having the same problem, but no fix has ever come from a user or the developers.
I'm desperate for a solution to this ctrl key bug, it's stopped me enjoying Shogun 2, even after buying the DLC for it, and I can't accept that after paying money into the product.
Some might say 'Just don't use the ctrl key' but as a long time TW player that is a lot easier said than done, the use of ctrl to select multiple units quickly is really deeply engrained in my mind, plus not using it makes battles needlessly harder to manage.
