The linked toggle for a block is broken and doesn't do anything when you have multiple blocks, some with extra products.

Steps:
1) Have block that produces extra intermediates
2) Have a second block that uses said intermediates
3) Set second block to linked mode
4) Toggling between product input and ingredient input mode now does nothing, it never calculates anything (and you can't input any values of course) and all values are zero

Bonus: Toggling link-unlink several times produces different results but they are also mostly unexpected.

Having the same issue. Decided to try just unlinking and relinking the stone from my iron production, and now it won't relink anymore. Same with other intermediates.

This issue should now be fixed
