Possible bugs after Update 36211?

So after some days playing the game since I bought it, I've been enjoying it very much, however misteriously after update from April 15th, I started spotting certain bugs that personally, have NEVER seen before:

1. This message popping up in-game, even in offline play. It's really annoying since the game does not pause when it pops up, and there is no way to disable it from appearing. Happened a couple of times, three times within 5 minutes or so. Don't know if it's still happening as of RIGHT NOW, but I saw it before yesterday.
2. During The Rise of Rome campaing, don't remember the exact scenario, music stopped playing, even when volume was up. There were two or three songs, but then it was muted entirely. Could be a one-time issue, maybe? Other user has reported it, but even then it seems to be extremely rare.
3. AI not attacking its nearby enemies. Also, if one was to attack a single unit from a group, then only the attacked unit would react, and not the whole group. I cannot bare this bug. Here's proof.

Do you know if these bugs were already there before, or were they indeed introduced with 36211 patch? Any help would be appreciated. I'll be editing my bug report thread if new details show up.
