why do I usually have my tank not on the screen or cant use the controls and why don't i get my crystals after battles in my battle fund?

it usually is not there or i don't get my crystals and stuff like that

😡

Please provide some screenshots.

Usually down to a slow internet connection or lag. Have a look at this: http://en.tankiwiki.com/Lag

ok but i never ever get the crystals i don't know how to get them!!!! i get them sometimes but not all of them

and i don't know how to do screenshots for some reason

How to take a screen shot?
How to upload an image?

nvm

its fine thanks anyway!!!
