It's not just a big base issue either, ever since they added the "Connect to..." feature, I often have quite spread out bases. Each individual section might be quite compact, but they'll be quite far apart. On my current base, the Core of it is 100+ metres away from the main entrance, and the Turrets are 50 or so metres further away than that. I quite like building modular bases using the "Connect to..." feature, but it does cause problems. Just to add, I too have had Drones stuck inside or underneath my base. This used to occur when Drones arrived while I wasn't close, needless to say. Scoob.
