I've noticed that missile troops in 1.5 are more cautious about hitting their own troops than they were in previous versions of total war. I suspect that there must be some check that the computer does to make sure friendlies are not too close to the target. It may be linked to that.
But it may be a CPU thing. For about a week, I would keep EB on my PC going all the time. The game would be on the strat map during the day and during the night - the theory being that it took too long to load the game, and I could use my laptop for things like email, etc. But I noticed that not only would this wear out my PC, but the units would behave oddly the longer the game had been running. This was especially true with cavarly never charging or even galloping. I solved all of this by just closing down the game each night.
So, to make a long story short, have you been playing for a long time without giving your PC a rest?
(I know nothing about how computers actually work; perhaps this second explanation is absurd).
