Sp Problem dyson sphere

Hi,

Ive got a Problem regarding the sp mission in dyson sphere. I am told to Do something useful until the antimatter chambre is completed but i am unable to Do anything or dock anywhere. Is this a bug or Do i simply have to wait?

You mean the airlock where i have to collect the generator? Allrady done that

Found the error. After returning from the nomad City it is fatal to dock with icarus. Thanks for the help
