Thanks for all the comments!:-) I was just so supprise of this Swamp thing...I have not even found the swamp yet,and they did not attacck my Base,but I was far from it..it lasted 4-5 days,until I went into the red circle (with new made weapond and armor) I allready had 2 dead stones there,I killed a few of them..they dissapear,the red circle was gone,,so I thought it was safe to pick my cart and stuf up from the water,then a new event started and here we go again...but at least now I knew what to do.....;-)
