hi , i must to add this commit for tdb 52 : https://github.com/TrinityCore/TrinityCore/commit/2da458c56d024aac04468ce2af454a83ad790bf6 but i have a error : The C++ Standard doesn't provide a hash for this type. Does anyone know how to convert this for compiler under VS 2013 ? typedef std::pair<int32, int32> coordinate; std::queue<coordinate> Q; std::unordered_set<coordinate> alreadyChecked; std::unordered_set<coordinate> outOfBounds;
