For some reason today I go into the garage and I look at the paints you could buy and now it is letting me buy paints that aren't for my rank so I buy a couple and im not sure if this is a glitch or something

Holy crap ever since this was put in this morning ive had 5 critical errors and I notice when the over drive is used I lag a lot, tanki needs to fix this problem because it doesn't let me play cause of it.
