Unable to launch Custom Battles on Steam

[Lysimachos]

When I try to play a custom battle this screen appears:

Script Error in TOOLS/SLITH_RANDOMMAP/UI/SLITH_RANDOMMAP.BSF
Failed to find variable GetPotluckMapType: Did you forget to predefine it?
Context: FUNCTION GetSkirmishPotLuckTerrain
type = GetPotluckMapType (mapSet); // Can‘t recycle the MPS version as we need to reuse Rand () here rather than FXRand ().

return type;

After that another screen appears saying

***Unhandled exception! ExpCode: 0x80000003 ExpFlags:
ExpAddress:0x750A0682 Please report!

And then the game CTD
It only occurs when I try to play custom battles.
MP battles have no problems.
Please, help me!

The same happens when trying to play a campaign or an epic battle ...

Having made some try it emerges that the problem is related to the "Rise of AI global mod".
When it is disabled there are no problems.
I tried also to disintall and reinstall it, but the problem persist ...

The current version of the Rise of AI mod is not compatible with the updated game. The mod author, roguedjack, is working on a revised, compatible version.

The reason that MP is not affected is that global mods are disabled for MP.
