What exactly should be the correct behavior/interaction ?

-

Not sure if that's the culprit, but debug removing it from the game will not make game crash in the savegame.
AI did once correctly cast Crater's Claws with Ferocious effect, crashed (maybe) before cast for the rest of the others savegame reload.

It also doesn't crash if you remove the AI's creature, so it may be an issue with the ferocious effect.

Guys it is the same bug with this.
The possible Trample + die evaluation of AI if attacks with Fanatic of Xenagos crashes game.
