I recreated over seven maps so far. For last four, I just run at random direction far away from spawning point (approximately 50 oxygen bottles). And there is no enemies - no creatures nor hives.
Question is - should I buy a lottery to benefit from such incredible luck, or I did something wrong?
No mods installed except of that one.
Difficulty - IDDQD

Well, my fault. Just need to wait a bit more - and hives will start to magically appear all over the world... Thanks a lot for quick answer!

you are welcome
