1.20.1_1.7.9: Not enough propellant, even though there is

[Verox001]

We properly built a rocket, but when trying to launch, we always don't have enough Delta-V. The flight recorder is saying that we don't have enough fuel, which is obviously false as you can see in the screenshot, where we have plenty of each fuel.

Thanks in advance for your help @RealAntEngineer!

this issue has been on the mod for quite a while. It happens somethimes with big rockets, there is in fact not enough propellant. Can I have a shematic of your rocket so I can test the issue ?

rocket_1.txt

Yes, sure! We're using a bunch of mods within the rocket, so I should probably send you our modlist as well (CurseForge Profile):
Create Ultimate Selection.zip

I had to change the file ending from rocket_1.nbt to TXT, because GitHub wouldn't allow me to upload NBT files.

Thanks for your help and happy easter!
