Thanks to PhantomII, all three objects
buildings.House$Med_Patio_03
buildings.House$Medievalroad3
buildings.House$Medievalroad1
are now available.
Exept buildings.House$]SEchurch10
But this buildings.House$]SEchurch10 is a problem not only of these uzav EastBalt maps, but of other maps as well. Some of those maps with such problem allow saving missions, some do not.
So, missions cannot be saved anyway.
Log shows these problems
INTERNAL ERROR: MeshObj: Can't load SIM 3do/Buildings/CSvsD1938/HangarKbely/live.sim
INTERNAL ERROR: Can't open file '3do/airfield_KDP/ConcretePlate1/Taxi_{-17}/mono.sim'
As to this airfield_KDP, I remember that someone shared these objects, but there is no folder named ConcretePlate1. The objects are available in my static.ini, but not physiically present.
I do not know where to find all missing objects, and what the log will show further if I find and install them.
Better to use Uzin's old less populated map than wasting so much time for looking missing objects. I do not remember any situation, which took me three weeks for rectifying problems with a map without success. I failed to find these objects in my 4.12.2 version with VP Modpack, though like in my 4.13.4 version all objects are available in 4.12.2 static.ini. Unfortunatelly, I failed to find a clue and cannot help with the successful result to share among users
