So, here's a things. I've been a few times in a situation where host start the game and nothing happens, I am still in the lobby. Maybe that was a random bug. But. I created a system with planets of all sorts and made em all starting planets. One of the planets was full lava, no land. And I could start the game, I've tried many many times. They I reduced "water" (lava) height, so there is an island and I could finally launch a game on this system. Now, I was in a lobby with some lava planets. Host started the countdown and again, when it reached zero nothing happened and chat didn't work (this always accompanies this bug). I've checked planet details using that one mod, and correct, one of the starting lava planets had lava height maxed out, so probably there was no place to land and it was starting planet. Devs should check this issue. Reproduction steps: Lava planet, no land, only lava, starting planet.
