I just thought I let you guys know this:
I ran into a problem, where the contract pack did not notice, that I already had solar Panels unlocked. My install is heavily modded (probaly most problematic: Stock Part Revamp), but, running through the mods I believed to be relevant, I could not find anything that would change the behaviour of this mod. I did not explicitely test it, though.
I fixed it by changing the StationCore.cfg as follows:
lines 262-265 are currently:
name = PartModuleUnlocked
type = PartModuleUnlocked
partModule = ModuleDeployableSolarPanel
I changed them to:
name = PartUnlocked
type = PartUnlocked
part = solarPanels5
This fixed the problem for me. Now the mod does not check if any slar panel is unlocked, but it specificly checks for the OX-STAT Photovoltaic Panel (the small, radially attached, not deployable one), which is usally the first one you get.
(Worth mentionning: ModuleDeployableSolarPanel includes ALL solar Panels.)
