1. The map sometimes freezes.
2. I bought the collector's edition through Steam, and I received two keys. Which one should I enter in the game to get the exclusive content?
3. Some achievements don't work. Is this really the case, or am I missing something? (Examples: I finished games with a hero, but didn't receive the achievement; I collected all the resources and killed all the neutrals, but still didn't get any; I bought all the units before the week of plague, and still nothing; I upgraded the Dynasty Staff to level 5, and still nothing).
Thank you in advance for answering my questions.
Regarding the key: one key is for registering, and the second is for the exclusive content. The exclusive content is entered in the main menu of the game; there should be an eagle icon in the upper right corner.
As for the achievements, there are many bugs in the game, and everyone hopes that the new patch will fix the shortcomings.
