For some reason, it's telling me that Item is uncraftable when i try and craft the medical syringe with level 2 work bench. I have all components needs but console and screen just says uncraftable when i try to.. Anyone able to help with this issue, as google has told me nothing. 

even when you don't use oxide?

Start by removing all addons

Then load them in 1 at a time until you can reproduce the error

IF your still having this issue on a vanilla server (or with no mods) Then stop the server, delete the steamapps folder on the server. From there re run the steam and oxide updates
