So here's the thing.
I decided to go ahead and mod my install, after seeing some of the wonderful things that exist via Scott Manley. So I went around and picked a few mods that looked interesting to me and installed them.
None of them said that they would have any problems with existing games, so I loaded into my career save that I've been playing on, and everything was going great. No problems, just smooth sailing-- or whatever the space equivalent of "sailing" is.
But after a while I noticed that my probes, bases, and ships were running low on power. I though, 'that's odd', and looked into why. Turns out, none of the solar panels in my game work anymore. I'm pretty sure that they still worked after installing the mods, so it must have somehow happened after that. For reference, here's a list (raw copy/paste from AVC) of the mods that I currently have installed:
KSP: 1.3 (Win64) - Unity: 5.4.0p4 - OS: Windows 7 Service Pack 1 (6.1.7601) 64bit
Community Category Kit - 2.0.1
Community Resource Pack - 0.7.1
DynamicBatteryStorage - 1.1
Extraplanetary Launchpads - 5.8.2
Kerbal Attachment System - 0.6.3
<b><color=#CA7B3C>Kopernicus</color></b> - 126.96.36.199
KSP-AVC Plugin - 188.8.131.52
NearFutureElectrical - 0.9.5
NearFutureProps - 0.1
NearFuturePropulsion - 0.9.4
NearFutureSolar - 0.8.6
NearFutureSpacecraft - 0.7.3
Kerbal Planetary Base Systems - 1.5.1
TweakScale - 2.3.6
So one of the symptoms of this problem is the solar panel parts not having any part info.
In the R&D center:
Same panel, in VAB:
One from Near Future Solar, VAB:
Stock retractable panel, VAB:
And for reference, one of the stock batteries, WITH part info:
To top it all off, I can't actually right click the panels like I should be able to while during a mission. This is a bit harder to show in a picture, so the closest I can really get is just highlighting the panel:
Sorry that last one's a bit dark, I should honestly have waited for Minmus to rotate, but I was rushed with the screenshots.
If anyone has any idea as to what might be wrong here, that'd be great. I looked around on the internet and I couldn't find anyone with a similar problem. And if nobody knows what the heck is going on, I guess I'll just backup my saves and do a fresh install and see if that fixes it.
And yeah, that's about it.
