OMG! Why does it not work

My card’s code will not work, every time I place a card it shows the switch is off but it still works how here look.

It happened to me to!
This must be a bug.

I doubt it’s a bug and is likely just visual. Can you send the link and describe how to reproduce the issue?

Okay here is the game. But it may seem off but my mechanics still work when it is off.

I’m not sure what the issue is, seem to work for me? or was something changed?
