This abnormaly occurs if you have numerous planets in a very small confinded space, my suggest is to either incrase the galaxy size or lower to number of planet
metersPerGalaxyUnit 25000.000000 -> pixel size of each galaxy (not sure but if you increase the galaxy size it does tends to space it more apart)
pixelsPerGalaxyUnit 2.619999 -> same here
what map did you see this on? While I've seen some pics of overlapping gravity wells, and this very funny pic of 2 colliding planets, I wonder if you can overlap a pair of gravity wells so that-
a. no need for phase-space travelling between them, since they overlap
b. overlap them so that one is at an alternate altitude (height) in relation to the other.
it mostly occurs on randomly generated maps
stange as it might sound, it mostly occurs on the huge and large maps
