Ok, got the following bugs so far:
1. Once Dreign declared war on me with empty message. (I understood it was declaration of war on next turn where I saw it in a news log).
2. "Next turn" disappeared once after reload of game, strasngly enough another reload fixed the issue.
3. Space miner in "Improvment standby" mode (when all mines are built) does not resume mining if "Mining" technology researched. You have to click manually "stop auto" and then it starts upgrading mines.
