Why can't you use the recombinator to upgrade maps anymore?

Maybe it's a glitch but it's not working for me. Why would anyone get rid of this? Now if i die on a 15 with no portals you are pretty much hooped. Gotta run 14s and hope another 15 drop at some point and the cycle starts again.

It's not the recombinator, its the reforge bench (3 to 1 trade). Tested and still works
