Everything seems to work fine when playing.
This has nothing to do with gameplay it is just saving your game to Roblox.
It gives you the error code: "Error: HTTP 400 (HTTP/1.1 400 Target and EventType parameters are required)." Meaning, that unless you have an event locked to a target area in your game that it is just a bad request with the communication from your computer to the servers. Look through all the parts of your game in the explorer and make sure that you have defined all of your events and extra stuff and see if that doesn't make it go away.
Error 400 - Bad Request - Most of the time there is a missing parameter, argument, or server communication error.
