Staging/Docking with Probes "No commnet" or Quick Save/Quick Load circumvent Commnet and wobbly reaction wheels

[BechMeister]

Hello! I am a 78h noob, currently building a space fuel station for further missions out to the Kerbol system. I read it was a good step to build something requiring rendezvous after getting people to the Mun. I am 12/19 stages done with the build i envisioned

I have in the building of this station relied heavily on "Remote Guidance Units" or Probes to get the parts into space. How ever.. when ever i drop the second stage i lose control of the rocket and it says there is no "No CommNet Connection" - See image below. 

Now! As i am a noob, i am not sure what a CommNet is... I have a feeling its a satelite network, like the GPS system or something (which i have not made) - but I can Fix/Circumvent this "issue" by quick saving and then quick loading.

It is not only this, I have relied heavily on a small "Tug Drone" i made for the purpose of assembling the parts in space... The ISS version of a forklift i guess. 

Here is a few images for context:

And two images of them working and doing their thing (sorry they are a bit dark)

 

These little guys also have the issue, that when they dock/undock they lose CommNet - they have antennas on them... and my space station has 4 huge disks.. so i guess they should be controllable around the station at least?

Any way, I also find, some times when i quick safe / quick load to get them going, its like the reaction wheel in them dont work. It wobbles and wants the center of the craft to be off center. This is also fixed by quick safe quick load.

Hope this helps with the bug slaying! 

PS. It seems like the relative position of crafts could be more precisely saved? I have noticed that when i quick safe to have a point i can load if i mess up the RCS maneuvering (which i relied heavily on in the beginning of the assembly) They were not were i saved them when i loaded... and i think this is what, some times causes the station to blow up... as it loads a vehicle within another vehicle. But I have not experienced this enough to be certain about it.. its just a theory.
