A shame the world will have to be reset... I guess there was no other option?
I have one request though, would it be possible to transfer a space station our faction had to the new world?
I had a look in the game files, and in the worldname/data folder there's the "spacestation_#.dat". By using NBTExplorer you can read the owner of the spacestation. The space station data itself is saved in the worldname/DIM_SPACESTATION# folder. If you could copy both the dimension folder and the spacestation_#.dat of our faction (owner of the spacestation is thom90) that'd be amazing.
Just tested this method on two SSP worlds and it worked succesfully.
(Note: we never had crashes caused by anyone of our faction, nor did the server ever crash because of us being at the spacestation)
One last thing: I'm willing to donate $10 to the server if you save our spacestation, perhaps that'll help
