Steps to Reproduce:
Turn on the Recipe Unlocking experiment;
Turn on cheats;
Use the command
/recipe @s take minecraft:planks
Observed Results:
No message ever shows up in chat, regardless of whether the command succeeded or not.
Expected Results:
The game tells the player when the command succeeds and when it fails.
Notes: This also occurs with the give argument, but it's not as much of an issue because a recipe toast shows up on screen.
Closing as fixed.
