I had a reactor with Blutonium in it before I restarted my game. Shut down the game normally with no issues. After the restart my reactor had no fuel in it. All the fuel rods were empty. I mined a piece of the reactor and put it back down to reform the multiblock but still was empty. Also after my game restart, all my reprocessors, fluidizers, turbine, and reactors were off. I had to restart everything. Just a bit annoying more than anything. I should note I'm playing ATM 9. I'm not sure what if any logs would help.
