Models from the game "We Happy Few"

[Smakkohooves]

I Tried by myself and after some problems i finally start to
have some results.
So i now have all the textures, and all the animated models.
But still have big issues with static models....

I tried to estract them with Umodel but the program crashes every time.
There are the issue report:
-------------
Serializing behind stopper (20FE+4 > 20FE)
FFileReader:erialize:File=MSH_Military_SockFolded.uasset <- FArchive::ByteOrderSerialize <- TArray:erialize:207/16842752 <- FStaticMeshLODModel4<< <- TArray:erialize:0/1 <- UStaticMesh4:erialize <- LoadObjecttaticMesh4'MSH_Military_SockFolded.MSH_Military_SockFolded', pos=20FE, ver=505/0 (unversioned), game=ue4.13 <- UObject::EndLoad <- LoadWholePackage:MSH_Military_SockFolded <- ExportPackages <- CUmodelApp:howPackageUI <- Main:umodel_build=1168
------------------------

Someone that knows these things can help me?
There are a alternative to umodel?
i now have a lot of "uasset/ubulk" that i can't open....
