Bug after hovering a variation

It seems if I hover a variation in game, and a move is made while it weird things happen.

Let’s say I’m white, and I view a variation and black makes a move while it.
The made move shows while I’m still hovering the variation, but when I unhover, the move black just made disappears, and the stone i’m playing shows up as the opposite color, in this case black. When I make a move, the result is white stone like it should, and the blacks move appears as well.
But if I make a move to the spot where black just played, it says “Error processing move” and then I can’t make a move until i refresh or analyze the game or something like that.
This is not maybe happening too much, because you don’t maybe usually make variations when you are playing, especially not to future moves, which this bug is about I think.
But it also happens when you view a game and share a variation (about a future move), that’s how i discovered this thing.
