Somehow your mod is overwriting the large hydrogen thruster, which causes a crash when you open the large blocks subcategory.
2019-04-09 00:59:37.272 - Thread: 1 -> No definition 'MyObjectBuilder_Thrust/LargeBlockLargeHydrogenThrust'. Maybe a mistake in XML?

There were a few other mods that I disabled, no change. Disabling Zeppelin fixed it. Too tired/lazy to make a new world and test pure Zeppelin.
Edit: Searching Thruster does not cause crash, but doesn't let you build it either.

Update: Starting a new creative world with only Zeppelin mod does not cause the crash when opening the Large Blocks subcategory, but I still can not build the Large Ship Hydrogen Thruster.

Interesting, that might explain another bug I have been toying with in MP. I've got a lot on my plate until Friday. I'll probably look at it this weekend.

Thank you!

i was able to get around the replacement problem by deleting hydrogenvent.sbc in the mod folder. server was spawning NPC ships with completely missing sections because of it

Ok that makes things fairly easy, thank you!

I too am having this issue. We had to remove it for now till it is fixed.

It seems you Hydrogen Vent is replacing the original Hydrogen thruster. Did you change the blockID?

I've got that fixed but I am in the middle of a light refactoring phase and have created a couple new bugs. Hopefully I'll have it out this week.

The hydrogen vent is still replacing the large hyd thruster and dragging the large thruster to the tool bar causes a game crash - removed this mod and thrusters are back to normal. Just letting u know.

I'm aware. It's finals week. This bug is fixed but I also did some refactoring because there were a ton of inconsistent spellings in the mod, but for some reason fixing them made the hydrogen cell conveyors stop working.

Hi, the blimp is still going up and down uncontroleable

It shouldn't be, have you added vents?

hy yes i had multiple vents on it but it didnt help

1) Large grid ships that enter 0 gravity (no horizon) start spinning uncontrollably if zeppelin control is left on, or is turned on while in space.
2) Gyros are not "let go" when zep control is turned off. Gyros will turn off automatically when I try and turn them on in the gyro control panel.

Both make my hybrid zeppelin/space ship sad.
