A bug with the revolt of the synthetics (Stellaris)

Created as synthetics ( for slaves, etc to play for the xenophobes ),started discontent, riots, etc. Finally came the revolt, with me has been spawned their capital and I began to assemble troops in one point, look, and synths his whole army to my neighbor distilled :\ Well I moved to the capital of the army, all the defenders quickly destroyed ( and the kernel) and conquered the planet. Like the end, but even after the capture of their capitals events continue with the destruction of my space ports.
