The Liquid Cooled Metal Reactor and Molten Salt Reactor (possibly others as well--I haven't tested them thoroughly) appear have resource tank anomalies when swapping fuel types. The LCM Reactor loses its EnrU tank entirely after switching off the initial 'Uranium-238 TWR' fuel setting, and the Molten Salt Reactor loses a Beryllium tank from its 'Uranium' and 'Thorium' fuel settings. Afterward, it is only present in the 'Thorium Breeding' fuel setting.

Steps to reproduce:

Liquid Cooled Metal Reactor

1. In the VAB, place a Liquid Cooled Metal Reactor.
2. Right-click the reactor. Note the current listed fuel (Uranium-238 TWR) and the tank filled with 50 EnrU.
3. Under the 'Reactor' subheading, click 'swap fuel'. The EnrU tank disappears, and does not reappear on any setting afterward.

Molten Salt Reactor

1. In the VAB, place a Molten Salt Reactor.
2. Right-click the reactor. Note the current listed fuel (Uranium) and the empty Beryllium tank.
3. Under the 'Reactor subheading, click 'swap fuel' two times, setting the fuel type to Thorium, and then Thorium Breeding. The Beryllium tank is set to full on the Thorium Breeding setting.
4. Click 'swap fuel' once more. The Beryllium tank disappears, and only reappears on the Thorium Breeding setting afterward.
