Is there any particular reason you’re using the Kistmet library? You can just do this:

YOURFILE.h

UProperty(BlueprintReadWrite)
TArray<FtileStructCPP> tileStructArray;

FtileStructCPP tileStruct;

UFUNCTION()
void RetrieveIndex(int32 index);

YOURFILE.cpp

void YOURCLASS::RetrieveIndex (int32 index) {
    if (tileStructArray.IsValidIndex(index)) {
        tileStruct = tileStructArray[index];

    }

}
