When entering water more than 1 block deep with a horse kicks a user off the horse and either despawns the horse or only kicks you off if you're really lucky. This happened with both me and my friend, both tried to relog. my friend was able to get back in the game however when it happened to me I left the game and relogged to get the horse to show like he had done but when doing so I got an "invalid issue" error or something like that and then thinking that restarting the game would help, it got even worse. Now I cant even click on realms otherwise it says "Please try restarting Minecraft" and i've tried restarting 4 times.
