Can't Move or Upgrade Buildings

Hi, the defence is not effected at all, when i hover over the building, i am still seeing the tooltip, the upgrade arrow and move cursor appears, sometimes you can move the building fine the 1st time, then trying to move it back, or any other building on top row afterwards, it does not allow you to do so, or with very very bad lag. I use google translate, lightshot, new tab direct and mcafee anti virus add ons, but i have always had these, for years. All of my bases are effected every single one.
