This was fixed in the live patch by setting a very low priority for the AI to build medic squads. Or something like that, I'm not familiar with how the AI scripts work. It shouldn't build more than one if it even builds one at all.
If this is still an issue or if anything else regarding AI is an issue we'd love detailed reports so we can actually look into these issues and try to fix them. Complaining "the AI doesn't work revert patch" without mentioning what's actually wrong gets us absolutely nowhere. We can't fix something if we don't know it's broken.
Nevermind then. The OP didn't say what was actually wrong with it so I thought the medic issue is what he was referring to.
