SAS & RCS not working

[Ayporos]

Hello,

TL;DR PROBLEM: SAS & RCS don't work, both are grayed out and unclickable.

I have recently begun playing KSP and enjoy it immensely. After fidgeting around a bit with a stock installation I decided to install mods to enhance my experience.
Most notably I would like some communication realism in the way of using RemoteTech, building nice functional space stations and building self-sustaining interplanetary spacecraft capable of replenishing its own resources (i.e. by undocking a smaller craft that can land on an asteroid/planet to mine & convert stuff to fuel).

After checking a bunch of mods (via 'top recommendation' lists, CKAN and other sources) I installed a bunch of mods (under 1.1.2) to find out that now my SAS & RCS don't work anymore.
It is not a problem with connection (RemoteTech) as I install antennae and have them activated before launch.

I gave up for a bit, and after 1.1.3 hit decided to do a full clean re-install and be more selective about which mods to use (to get the core above mentioned functionality at least working and then possibly expand from there).
Yet again SAS & RCS does not work.

The reason I made this thread was in the hope of being pointed out what is going wrong by someone who happens to know or has experienced this before.
I would hate to have to manually trouble-shoot the issue myself which would take a long time while someone else might already know the answer.
Thanks in advance in case you can help me and if not thanks for reading anyway!

I run KSP 1.1.3 64bit mode under win10 from steam (installed on an SSD). I have a 6-core XEON processor with 48gb of RAM (doubt it is relevant but whatever).
