Pinging Removes my Cursor

I don't know what exactly causes it to happen, and I haven't seen it in other places. All I know is that sometimes, I'll be in the middle of a game. I'll ping I'm going somewhere, and my cursor vanishes. I can still see where I'm going because of the green arrows when I click the ground, but it makes it almost impossible to fight or buy items.

I tested it out a bit in customs, and it didn't happen at the start of the game, so I don't know if I have to get a ways into it before it happens.
