Did you put it into Coremods?

 

[MrXANA91]

Yes... Galacticraft is in coremod folder, and forge is correctly installed.
The buggy does not crash the server when i broke it, this is only for the NASA workbench.

Edit : Oh, I realize that i didn't explain my problem.
When im breaking a NASA workbench block, all the structure disapear, the server reports a crash, and when i restart the server, some invisible blocks still here. Strange =/
