What patch did we start seeing Nations putting their main armies in colonies?

[Vampiresbane]

I've seen it a lot lately and it's causing me headaches (well small ones).
1st my ally France doesn't defend itself because its main forces are in the Americas (my Byzantine -> Rome game)
2nd I can't seize Cape Verde from Portugal because they have their entire force limit there (Independent Sicily game)

What patch should I revert to in order to avoid this new AI issue? What patch did we start seeing this odd behavior?

I've seen it for at least half a dozen patches. Ferrying 20k to a new colony is common in my games for Western Europe.

They've done it since the earliest days of the game. How often + how large a % of French troops are over in California varies patch to patch, but I'm not aware of a patch where the AI would never do it.

One of my favorite memories is still watching AI France get > 50 regiments strait trapped by a cog or two belonging to my Alaska CN.
