It has been reported that items which are now available on vendors for sale but are also crafted items can not be deconstructed.

I have verified this and provided a detailed description for how to replicate this bug to our technicians as of early this morning. In short, stackable items may not be deconstructed, but in order to sell items on a vendor, they had to be made stackable.

I do apologize for any inconvenience this causes and will continue to monitor the situation until it gets resolved.

Thank you for your patience while our tech team works on a fix.
