Hello!
I'm having a problem that's maing the game pretty much unplayable (unless you're crazy enough to play only with SRBs and the twin boar that for some reason does work).
All stock fuel tanks (be it liquid fuel+oxidizer, only LF, monopropelant or xeon gas) apear as purely structural/ornamental parts. Idon't know if it's a mod that causing it (didn't open the game before installing mods) or what.
This is a fresh instalation (new PC stopped working, had to go back to old one that didn't had KSP installed).

The mods list, add kopernicus (it didn't fit):

The game is pretty damn hard without liquid fuel
Oh, also Strategia is showing me the Kerbal system strategies and I have installed the Galileo´s Planet Pack.
