So I downloaded the demo before buying and I have this problem in the very start of the training, I can't connect back the command module or anything once disconnected it, I can only connect the fuel tank to the side of the module( which looks silly). Can some one tell me if this is normal and I'm just noob, or this does not happen in the full version? image of the issue ---> http://imgur.com/47nMOVI Thank you for your help ^^
