1- I receive threat messages from other civs, even when they are my allies, like "show yourself and meet me face to face !"
That sounds like the bounty response -- whenever a bounty is placed on a computer, he automatically spouts a "come out of the shadows!" type of response.
2- Like the No1, the same opponent can send me a compliment like "I like the way things go between us" and a minute later, without any activity, I can receive a threat from this guy.
Diplomacy system is being improved, but it sounds again like the above -- the message goes to
everyone as a response to the bounty being placed.
4- Sound effects problem. With the same configuration, I did not encounter this bug in BETA 2. The music is fine, but the effects (like in a battle) are inconsistent (or jerked... but I'm pretty sure it's not the word I must use in english. Google told me to use this hehe)
Do you mean jerky?
5- Like No4, some graphics problems. I noticed once that a ship movement in hyperspace was the opposite of fluid
What do you mean, opposite of fluid?
