Staging and Kerbal video feeds not visible at launch problem

[semperfikurt]

So when I try to launch my vehicles I go to the pad and everything works fine but the staging and video feeds of the Kerbals inside the pod don't show up. Also the Stage light is purple instead of flashing green. I can select any part and all the various functions work fine, just no staging control (can't launch), and also no IVA. Originally I would just restore some of the old Spaces files for pods I got rid of back to the GameData folder and that alleviated the problem for a little bit but now it happens consistently regardless of the build or pod I am using. What could be causing this?

I am using a pretty heavily modded install of KSP. I have parts from 20 different mods, generally only a small handful from each after I get rid of all the stuff I never use. My GameData file is 1.02G. Anyway is there any solution anyone knows of to fix this short of tossing a bunch of stuff out?
