Yeh my questions have been answered. Thx

Hello, so I haven't played this game for almost a year and half, and when I came back I am confused with some things in the game. I hope you don't mind, I have more than one question. 1. In battles when I join I often can't do any damage to other tanks, I have to close the game completely and restart it and when I am back, then it works. Then after 30 mins or so, same problem. I am pretty sure it's not lag problem, because i can take flags, pick up the boxes instantly and everything else and game runs smoothly. Why is this happening? 2. Second question. Also sometimes i have an error, during battle the game freezes for short time, and after it unfreezes, entire screen turns gray, only sound works. And again I have to close the game and reopen it to solve the problem. This usually happens after I played 5 or 6 battles. I played this game for years, and I see this for the first time. Why? 3. Ok so third question. It's not connected with any issues. Why is tank invincible for few secs when it spawns? You can't damage him, but he can damage you. 4. Ok last one. So you need WO1 rank to participate in custom battles or to create your own battle, but confusing part is that you can still choose lower ranks to join your battle in battle settings even if they're not WO1. I saw players that are lower than WO1 playing in custom battles. How?

"Foul play discovered. You have been disconnected" XD, does anyone remember this?
