This is a known problem in any mod that has moons larger than tiny. I expect your homeworld has a small or medium oxy/rock moon and the neutral race has a hydro/ice moon. Those are the planets that the game looked at when choosing the sectors for your homeworlds, but it then planted them on the main planet. To avoid triggering this bug, you'll have to play with good starting planets, as that requires large homeworlds and there are no large moons in Adamant. If the largest moons were merely small, average value starting planets would also work without problems.
