Windows Grandpas Shrine - Cannot use it again

Newcomer
We got the Steam version of the game, 1.5.6 (Hotfix 3) and play multiplayer with 2 players.
We used grandpas shrine once, when it was "the time to do". I got that statue, she did not.

As the website stated, with version 1.5+ one can use it again, insert a diamond and get "the calculation again". We tried that to have "more perfection :D" and for sure, to get that statue so she also gets Iridium. But we can both not use the statue again, no candles are burning, only the name "grandpas shrine" is shown on the screen.

Is it a bug or does it not work in Multiplayer?
