Farm heroes -level 267 -playing on Facebook - reload message

game fails at third spider movement - a reload message appears - if you do not reach the third web then the message appears immediately on the next attempt at the level. also at the first loading of the level you are told the highlighted square is blank i.e. has a web - it isn't - the blank square is to the left of the highlighted one. I see other players have had the same problem - is there a solution ?
