Chesspot rifle

Upgrade to excellent workbench and add augments. Bench is now with maxed augments with cannon and ammo box being the last to create. The Chesspot rifle is not listed even though the plan is known. Solution - destroy bench and move away from augments. Create cannon augment and the item is now able to be created. This also applies with some other items. No being able to interact with an augmentation or being able to understand why an item can not be created is frustrating.
