Vehement and Aberrant not leaving the system with portal.

[Pistachio]

My current game has the extradimensional crisis going on.

Problem occurred with the Vehement and the Aberrant spawned into the Unbidden's territory, as the two extra factions got stomped out by the Unbidden from the start.
However, at this point, the two new crisis factions were leaving their home system without a problem.

Right now I have wiped out the Unbidden, with supposedly 2 more anchors still somewhere (not sure where), but no more fleets are in the galaxy.

Problem now is that the Vehement and the Aberrant are not leaving their home system and are just stockpiling fleets. There is no way I'm going to jump in there with a winning chance.

Is there a way to fix this issue?
