We should be able to pick up the workbench within 2 minutes of placement, like the demolishing of a wall. So if we place it wrong initally, we can pick it up and try again. After two minutes, the pickup option should be grayed out.
It would need a rule that if damaged this feature is terminated early - to provent greifing raiders.
Wich raid only goes 2 min ? after the raid your base is stocked. Same as with walling in. Works fine right now.
