Shop showing wrong unit

Hello friends,

your boy Platy from Twitter sent me over to post my clip here.

It's a pretty basic but at the same time pretty annoying bug, where the shop shows a unit but when I buy it, I get a different one. I only had this bug once though. I don't know if there's a specific way to reproduce it. Also I clicked on the graves next to it (just in case the graves was a hidden varus), but it didn't let me buy it so I'd assume, that this one was indeed a graves.

Hope this is an ez fix.
