I think I’ve discovered a bug. When I try to refill my energy, the green refill button sometimes turns into a half-sized green button with no text. When I press it, this appears. https://ibb.co/MkxdSqT9

It’s not really a major bug, but it has already happened to me 3 times. The first 2 times happened consecutively, and the 3rd time happened just now.
