I was trying some El Cid 5 on HD version, it start like this

The gate never opens, AI barely does anything. I got some bugged version.

Anyone knows how to fix? I don't want to beat this level easily because of this bug.

Edit: Chazzy just did a run on the bugged campaign, guess I'll see whether it is legit. Oke, got contact with developer, missions can be bugged since patch 4.0, atleast this one is. Can prevent by playing 3.9. Or just use this bugged version for IL timing.

To go back to earlier patch:

1. Go to your games library on Steam, and right click AoE2HD.

2. Select "Properties" from the dropdown that appears.

3. Click the tab called "Betas" in the window that pops up.

4. Select "Archive3.9" from the dropdown of beta programs you can opt into.

5. Let it download, and then launch AoE2HD once the download is finished. You should then be on 3.9

That's really bad news, that it glitches out on 4.0. I hope it's isolated to this map being broken...
