Bots Freeze if I pre-Move

A lot of the bots have been freezing when I pre-move, I've refreshed the page but once it freezes I always have to surrender. I know the simple solution is "Don't pre-move" but like, this is clearly a bug. Help. 

Why would you pre-move against a bot? They play the same whatever the time control is.

It's been reported and staff are looking into it

I have found that if you pre-move playing bots in bullet (1 min), they sometimes have mental breakdowns and time out. I confess it is fun beating super-grandmaster bots but, it must be a bug because there is no way the site builds nervous breakdowns into its bots. Has anyone else experienced this?

The bots engine cant handle the instant move causing a synchronziation issue which forces a reload of the website

id like to elaborate, when you premove the bots engine fails to incorporate the current move sequence into its internal script. Premoves are stored locally on your device and only sent to the server the millisecond the bots move is received. When you premove, multiple moves hit the server simulatneously. Premoving sends moves at speeds the engine isn't optimized to handle. The premoves can overflow the bot's input buffer, causing it to time out or stop responding. If your moves arrive faster than the engine can finish a single evaluation cycle, it may suffer a mental breakdown and stop responding entirely, causing you to resign or refresh. Basically, the bots break because your instant premoved inputs arrive faster than the server can synchronize them with the bot's rigid opening scripts and engine calculations, causing a logical "desync" that lead to freezes, illegal board states or total engine meltdowns.
