Hydrogen tank not filling.

[TwUnix]

Building a small ship, my first one. Putting ice in the H2/O2 generator, hydrogen thruster has orange glow, but hydrogen tank isn't filling up.

Is it connected properly ?
Note that the H2 tanks fill very slowly compared to O2 tanks. It takes a while until you see the first of the four green lights, try and check the block data in the control panel. If you don´t see any percentage filling up your connection to the H2/O2 generator might be faulty OR your engines use H2 faster than the generator can supply. In this case you might want to turn on only your generator and your tank.

I came here because I was having problems with my H2 tank not filling. Tried all sorts of things. Turns out the H2 Engine was running and it was using all of the H2 the generator was making. When the engine shut off the tank started filling. It makes total sense but sometimes that's the sort of thing that drives us batty.

A new "did-you-know?" thread would have been appropriate.
