yeah sry mate but dont blame the game, you made many mistakes sry to say.
There are many Youtube vids on securing and digging moths/bases.
Best tip i can give is digg from N to S, or E to W...always along these lines to get perfectly strait lines.
And always keep your pets+foods far away from compound walls and moths(minimum of 20m ill sasy).
If your building in mistlands forget my tips:)
