Losing a hydrogen tank disables the hydrogen system
A Large-Grid Small Hydrogen Tank was destroyed and it caused all my hydrogen thrust to stop working
I have my main ship, which has millions of Ice, plenty of H2/O2 Generators, and several Large Hydrogen Tanks all filled to about 40% (not set to Stockpile)
I had a module that connects to the front of the ship. That module has 1 Large-Grid Small Hydrogen tank and the other blocks needed so it can keep itself still in space
I slightly damaged the module and it happened to break the Large-Grid Small Hydrogen tank. That should not have been a problem except every single hydrogen thrust I have stopped working
I have almost 2500 hours played. I checked all the possible problems. I tried all the solutions like cycling power, turning blocks on/off, toggling stockpile, etc. Restarting the game fixed it. This is a bug, and it can break entire ships.
