After in the second room (after the schiffer explaination) with the italian language the game crash. With the english language the game does not crash.

The same problem with spanish language

Thanks for the information. They fix it in the next patch.

Not only at the beginning, but also in some sequences of the game. Occurs in Spanish not in English

I'm at the Cesare Palace right now, but in Italian only that sequence always crash (I don't know if I will get another bug before the end of the game, but since the Cesare Palace is the last setting maybe I will not)...
Still there is another crash section in the game (but it also crash with english audio), it's the first challenge on the Pirate Island but it only occur at random after many tries and also when your last roman is a skeleton from bronze to silver (I think, I'm not really sure what make the game crash there).

I was able to complete that challenge only at Normal difficulty (to make the challenge fast), I'm playing all the game on hard difficulty by the way.

Aside from these 2 bugs (italian language in the tutorial crash, pirate island first challenge crash) it is bug free for me (still, I have to finish the game... maybe I will get a new bug at the Cesare Palace before the end....).

It's weird but as you say I've also had random errors. Maybe they can check it in future updates
