NHF – new heroes for Heroes V 3.1.

Try putting SetObjectEnabled and Trigger into startThread functions. I don't have the ability to test the script under these conditions (even on a "powerful" machine, it takes several seconds to load :().

On my fairly powerful computer, it's the same. But on the configuration mentioned above, it's terrible. The game settings are already set to almost the minimum.

Random map in Heroes of Might and Magic.
Without disabling objects, it loads faster. But here, all the other scripts are likely influencing it as well.
Out of 5 attempts, the map froze 4 times, and once I didn't even notice it against the general background.
We'll keep testing...
