you have no idea what crashes so why blame it on the hosting? If the connection would be **** then you can maybe look at the hoster but the connection is great. It is just servers which are not completely stable, it's early access...
Also, MP is not the main focus from Bannerlord, this has been said many times, the main focus of Mount&Blade has always been SP. Look at how many players play Bannerlord (200k at the same time) and how many are queuing for a server (100-1500). Less than a percent of the players is in MP at the same time.
