I've checked both HAVEN & MILKY WAY campaign starting maps just to be sure & they had them all properly validated. My buggy condition seem to occur only while in any kind of SandBox modes of Intrigue.
Soooo.. either i had an install flaw when purchasing that crazy deal on Gold Edition (v3.10 with all DLC) recently -- or, key files aren't initiated correctly. And before anybody should ask.. yes, i already verified Steam files.
