That hotfix does not appear to address the same issue. It only includes Heba, and even the new version that you just released is showing this issue. In fact, the issue has returned because, after my post, I fixed it with the following addition to both Heba and Lominia:
Template
{
name = Laythe
removePQSMods = PQSLandControl, PQSMod_AltitudeAlpha, PQSMod_VertexHeightNoise, PQSMod_VertexSimplexHeightMap, PQSMod_VertexHeightMap
}
Once I added this, in the old version, it worked. So I added it in the new version as well on a test copy of KSP and.... it works as well.
I am not sure this is the right fix, but, it does work. Without it, if I go into the science archives (R&D Building), Wernher's face doesn't load and no children of Valentine can be seen in the list on the left, even after selecting Valentine.
Once I add the templates, it all works as expected. This is with no other mods installed except Kopernicus and its requirements.
