#jira UE-74857 Change Soft object harvesting for local variables to use a temporarily constructed UFunction instance instead of type-specific hacks Add FindSignatureFunction and fix function entry tooltip to work for newly created functions Fix the soft reference fixup code in K2Node to handle references inside a struct, and update CustomEvent/FunctionEntry to update their user pins defaults after a fixup to editor pin data Right now only local variables are using the value cache as we have too many blueprint pin defaults that cannot be safely copied into properties, will re-evaluate later and fixup comments #rb michael.noland [CL 6593293 by Ben Zeigler in Dev-Framework branch]
