@Vanamonde i was trying to install Kerbal Konstruct, Kerbin Side Remastered (Repo for this one lack more information) and GAP for better airplane gameplay
It was hard to find information about versions and exactly what these mods does together.
My first though was that they only add missions and static sites to the game, turns out when i installed they added interaction with buildings, ability to buy launch sites and assign scientists... I was trying to keep the core mechanics vanilla as possible, these was unwanted additions. So i disabled these mods
To sum up i still don't know which mod added this and how to disable these features. With the forum would be easier since all information is condensed here
