Wrong piece moved on premove

In a few of my bullet games, I premoved Nfd7 but Nbd7 was actually played. It hasn't happened to me yet but I've also heard of something similar happening with rooks. I can link to a few of the games if you want.

The one with the rooks might have been me, it wasn't a premove though, I just grabbed the Rc, but dragged the Rh instead

Actually it was @yoavjm_2004. Weird.

Same here: https://www.chess.com/live/game/3509779340 

On move 18 for black (me), I premoved Raxd8, but somehow Rexd8 was played

Thanks - working on this!

I've got a different bug where I premoved a lot of rook moved that were repetition (checks on the 6th 7th 8th rank) so I was premoving a lot and sequencing, when all of a sudden my timer starts running out instead of the opponent's, but I couldn't make a move. 
Wish I was recording but I was just hanging around and playing. Maybe it happens when you premove a lot, I don't know what triggered it really.

Yep, happened to me 2 times earlier as well

It is a very disruptive one.
Luckily I managed to draw because of the repetition, or else I'd have lost because of the weird bug.
Here's the game where it happened:

After White's 53rd move is where the bug happened. With barely 2 seconds left and stuck without being able to move my pieces and my clock running, I had the idea of clicking the Draw button and *phew* 

And I drew (due to insufficient material) a GM where I premoved a mate

Thanks!

There is something extremely wrong with premoves. This was the game:

I'm 100% sure I premoved correctly to checkmate with 3,5s left on my clock and 0,1s on my opponent's clock. It's forced mate, Qc2, Qb3# I saw all my premoves displayed, but then my time started running out and I couldn't move my pieces, since I guess they weren't displayed on the position they actually were on the server side. It's extremely frustrating to lose like that. I premoved with the pawn moves to promotion to mate

I don't know why it happens an how to resolve it, but until then I'd suggest having the premoves be "ghost" duplicates and the piece staying where it is. Because when it loads the actual position seems to be after the game is lost.

edit: here is the link so the time is also visible https://www.chess.com/live/game/3518716886

It happened again, instead of doing the premoves, it just becomes completely locked while the time runs out https://www.chess.com/live/game/3521454226

That happened to me too.
