Buggy doesnt respawn after dying

[Barnaby Dent]

Every time my buggy dies (has happened 3 times now) it does not respawn. I get the timer to say when it will be back, but then after that time it isnt in the ant nest, i cant call it and when i go on the buggy menu then the ant icon is there but its locked and wont let me call it (says its unavailable). THIS IS VERY ANNOYING AS I HAVE HAD TO GET 3 NEW SOLDIER ANT EGGS WHICH TAKES SO LONG  please stop it
