our team got dced, when we came back we were all lvl 1 and couldn't cast abilities or spells.

i was playing a game, and i am curious if you guys have experience this. we were playing, this was late game, we were all about lvl 17-18. our whole team dced. just our team, not the enemy's. and when we came back were lvl 1! and we couldn't cast any abilities or spells. we were stuck doing autos. i tried taking a screen shot, but when i put it on a gif it showed up all black. like if i took a picture of a blank screen.
