Island of a small skull

I’m almost finished with this map. Once I’m done, I’ll give a detailed review. Right now, I want to talk about two bugs I encountered (I’m playing Heroes of Might and Magic, maybe they don’t exist in a clean version of the game). Has anyone else played through it? Did you experience the same thing? I’ve checked both of them several times: each time, it’s the same. 1. In the battle with Inteus, the phoenixes are resurrected twice! That is, there are initially 300 of them, I kill them – 60 are resurrected (as it should be), I kill them again – and another 60 get up! And only then can I kill them permanently! 2. A little later, I summon a boat, and it appears on land! Moreover, it can appear in one cell or another! I calmly get into the boat, and I calmly sail out to sea. But I can also sail on land – although not very far! I don’t understand what’s going on. I examined this area in the editor – as far as I can tell, everything is normal there. It’s a miracle!
