Getting this error having upgraded my PC build to 4.8.0 Preview 2
UELinkerFixups.cpp.obj : error LNK2019: unresolved external symbol "void __cdecl EmptyLinkFunctionForGeneratedCodeOnlineSubsystemSteam

Stubbing out the functions myself gets me through linking but seem unlikely to be the correct solution
