Study desk requires 4 bone glues - 40 bones. It's a must have structure. Collecting 40 bones in early days is pain in the ass. It was tough even before you make our life tougher - added "chicken run" patch. After this patch it's even more pain in the ass.
Please consider change there.
First option: I think 2 bone glues are more than enough. Boards and block of wood are not a problem.
Second option: Change bone glue to another material, more accessible in early days.
