GalacticCraft 1.12.2 error

Using: spongeforge-1.12.2-2838-7.3.0
Using: GalacticraftCore-1.12.2-

Problem is: I can’t push “launch” button while i’m in space.
I mind, i have started my rocket, flied to the space and i’m in planet choose window. Normally i’m clicking on planet and next pushing “launch” button but i can’t push this button. I stuck in this window. I can’t return to overworld or do anything.
That does only on spongeforge, when i tested that on another engine, that worked.
Please help me, i need galacticraft and spongeforge on server.
