Read acccess violation in Map::getRegionDistance #3

Description

@spacehamster

If i run the following

#include <mapgen/MapGenerator.hpp>
int main(int argc, char ** argv) {
    MapGenerator * mapgen = new MapGenerator(1600, 900);
    mapgen->setSeed(4000);
    mapgen->update();
    mapgen->startSimulation();
    delete mapgen;
}

I get a read access violation in Map::getRegionDistance trying to read from std::shared_ptrr.
I think this may be related to passing in a raw pointer Region * in Simulator.cpp makeRoad
and then casting them back to shared_ptr in LeastCostEstimate?
Or in AdjactedCost the micropather is given a reference to n which immediatly falls out of scope?

I tried changing

int result = pather->Solve(c->region.get(), oc->region.get() &path, &totalCost);

to

int result = pather->Solve(&(c->region), &(oc->region), &path, &totalCost);

and

for (auto n : r->neighbors) {

to

for (auto &n : r->neighbors) {

in AdjacentCost but then it crashes while trying to delete cities in removeBadPorts
