Possible to put reagent on locked tile

[yancouto]

On the enemy that locks some of your tiles, you can still put a reagent there if you choose a recipe that has ???? and then right-click the components to make them go to the board. I didn't check if it's possible to actually combine them once they're there.

Repro steps:

Go to enemy that locks the middle tile

Choose a recipe with 4 question marks

Right click the element in place
