I lost the ability to control probes?

[Offensive Scientist]

Let me first state that I am a KSP veteran despite what this these forums say. I have been playing since around early 2013 with over 1000 hours. Anyways, I have been playing recently and noticed that I cannot control my probes anymore. It is really odd. Even with the proper antennas. I do have quite a bit of mods, but the issue did not arise after I installed a mod. 

B9 Aerospace,B9 Aerospace HX, B9 Aerospace Legacy, B9 Animation, B9 Part Switch, BDArmoury, BoulderCO, Chatterer, CommunityCatergoryKit, CommunityResourcePack, CommunityTechTree, Engine Light,  EVE, Firespitter, Hangar Externder, IFS, JSI, KAS, Kerbal Engineer, Kerbalism, Kerbal Joint Reinforcement, KerbalKonstructs, KerbalTek, KerbinSideREmastered, Kopernicus, KS3P, LoadingScreenManager, ModularFlightIntegrator, MP_Nazari, Nasa Countdown, Patch Manager, Physics Range Extender, Planetary Base Inc, ProceduralDynamics, ProcedualParts, SCANSat, scatterer, SmokeScreen, SVE, TRR, Tweak Scale, Vaporvent, Warp Plugin.

Quite the number of mods. I dont think it necessary to really show my specs but just in case:

Intel I7 7700

GTX 1080 8GB

16 GGR4 RAM

1TB HDD, 256 GB SSD

I am thankful for any help

Be a little more specific.  Commnet connection? How can't you control them, etc...

This would imply that it is a stock issue, which it most probably is not.  It is probably caused by a mod, and it altered the commnet ranges, but you never noticed it till you got out of range.   But without more detail in what exactly is happening, it's hard to diagnose.

Most likely to be a commnet connection problem, even though you are using a proper antenna. You can test this easily by deactivating the commnet in your difficulty options. You also got a little symbol  the top left corner while controling a probe (looks like the 'probe' symbol shown in the map view, next to the signal strength). This will provide some additional informations if you hover your curser above this symbol. Can be 'Full control' (green symbol), 'no control' (red symbol) and depending on your difficulty settings some kind of 'half control' (orange). What does it show to you?

Which KSP version do you use and did is your savegame created in another KSP Version? Does this also happen if you create a probe in a new savegame?
