In the middle of the Dungeon, I have a large lake. The background is black, so without lighting, nothing is visible when moving on a ship.
Let's try a "perversion," I'll give it a shot.

Ment was right, using torches and crystals will cause fewer problems. :D
In general:
1. We 'hide' the ship, already with lighting, in an inconspicuous place.
2. We place a trigger on the shipyard.
3. Upon contact with the shipyard, we teleport the ship to the desired location, i.e., near the shipyard.
...yes, here you'll also need to play around with the ship's price, the purchase message, etc. :smile33:
It's not that difficult to figure out why the computer isn't attacking; send me the map draft (you can send it in a private message), I'll take a look and maybe I'll figure out what's going on.

1. I made the map, everything is fine, but the opponent (the computer) doesn't engage in battles (even against 10 fey with 150 zealot dragons), it only picks up easy loot. I didn't use scripts. What's the problem? Do I need to set priorities for the computer? If so, how?

Here's the corrected version of your map. + A script opens the fog of war - on the 3rd day (Talanar), the computer killed the griffins. (sent in a private message)
I have version 3.1, so you messed something up - it seems you were trying to make a Campaign, as a result, extra folders with incorrect paths appeared, and that's why the start was impossible. It also didn't load as a Campaign.
Check it - everything should work, everything is fine for me, so I don't think you'll need any priorities for the computer. :cool:
