Is the creating space mod broken for anyone else?

Apent an hour working on trying to make my giant spaceship work and sfter having tons of issues with weight depsite having enough rockets and methane to make the ship out of instrad i gave up and made a dummy ship to test-

A tiny platform i stuck 4 giant rockets and 5 normal ones on after the game kept complaining about weight. Finally get thst handled when I have nothing but a skeleton if anything for a ship to stand on. I try to fly and oh but now a dozen blocks arnt the issue it's rhat I have more than enough fuel.... what

160 oxygen and methane out of 0.81b

I tried to make the fuel just right, even mimicked the ponder ship and nothing works. I have enough fuel stuff but the game says that's too much or isn't enough- If there's a better create space mod lemme know because this is royally irritating me. This mod has got to be broken.
