Guys, i've send you 'in game' bug reports for X times with screen shots and explanations. After the village population reached a few hundreds vikings some of them will be constantly teleported to the main building from which they go straight line to the shore to be teleported back. They don't work, eat, rest until they die in the loop. The bigger the map the sooner it is a problem. Making a save and reload is the solution for a short while but with the population of about 1000 you need to reload every 5 minutes.
Don't produce bigger new maps - produce bug free game first guys !
BTW. Nice work
