Division by zero in spawngroup.cpp:
int totalchance = 0;

LinkedListIterator<SpawnEntry*> iterator(list_);
iterator.Reset();
while(iterator.MoreElements())
{
totalchance += iterator.GetData()->chance;
iterator.Advance();
}
sint32 roll = (rand()%totalchance);

Also there are occasional exception errors in regards to the spawn door code (which also crashes everytime if you dont have the new door db).
