Can't Undo When Clicking the Shell for Replenishing the Nursery

[Carbonate]

I accidentally clicked the wrong shell - the one that lets you immediately place a new Station and replenish the Nursery. I did not want to click that shell, but unfortunately once I clicked it, I was locked in and I had to proceed with placing the new station and replenishing the nursery. Can you please fix this and add the Undo function? Thanks.

This can't be undone because it reveals hidden informations (the new corals in the nursery and the next station)
