I've still been playing against M27 with some friends. I haven't shared any replays recently because there wasn't much too noticeable for a while, but we did have a few games in a row on a map generator map in which one of the enemy ACUs just walked straight into T2 point defenses and died. I did built T2 point defenses relatively early but I'm not sure why it didn't retreat once it was getting hurt. This is the replay URL: https://replay.faforever.com/17728462 there were also a few other games on that same map where the enemy ACU did exactly the same thing and died so it seemed to be a recurring issues.

All of my games are titled TyneTest and most of them are against M27 with a few human allies and sometimes M27 allies so if you want extra random replays just search them up. Other than the one issue noted above, the M27 is still giving us novices a run for our money, we often beat it but it does often manage to beat us too by rushing experimentals or T3 artillery.

Various tweaks aimed at improving M27’s response to a nearby naval threat slightly

Thanks for the acknowledgement; here's a couple more replays if you want:

It was 2 games of 2 humans VS 2 M27s on Eye of the Storm. We lost the first one but won the second. There didn't seem to be any major bugs but in the second match, the bottom right AI sent its commander diagonally across the whole map underwater which meant that it was completely vulnerable to torpedoes. So it almost got taken out by a lone T1 submarine. We lost the first match in a big part due to the M27 firebases being quite effective and me not defending against the T2 artillery quickly enough; however, in the second match it didn't really seem to build the firebases as effectively at the top or bottom so we just skirmished across gradually.

@maudlin27 - example of navy game: I've played a few games with navy now and it seems to be working well. In a few games it has used the missiles on the cruisers to great advantage. Here's a Setons game I just played with 7 M27AIs + me and it seemed to work well; I didn't notice any major mistakes made by the AI; however, two of my opponents commanders were killed on the land bridge by the M27 opposition so they were maybe being a bit too reckless with their commanders: https://replay.faforever.com/17979113

The latest updates seem to work well. I've had some good games on maps like Flooded Strip Mine when the AI navy seems to work pretty well. One weakness I found in recent games is that the AI is sending their commanders forward fairly far into the game and they're relatively poorly defended in general and definitely poorly defended against air. If you try to go air too early the AI seems to adapt and defend fairly well but if I don't go air at all early game and then when their commanders cross that map towards me, spam a whole lot of T1 bombers very quickly I can almost always snipe the commander/s. Other than that it's really challenging though as it is still beating us quite frequently with either nukes, artillery or experimentals. Here's an example replay of sniping the commanders with T1 bombers: https://replay.faforever.com/18219133

Frequent lack of anti-nukes?... I've noticed that quite often in games M28 doesn't seem to be building anti-nukes. When I've had M28 allies, the game has often very easily ended by either my M28 allies or M28 opponents getting nuked my an opposing M28 AI and having zero anti-nuke defenses; because it is the opposing M28 sending the nukes it is not the case of the nukes being too fast for the AI to build defenses, it just seems like the AI isn't building defenses. Here's an example of a replay: https://replay.faforever.com/20218155
