Blitz / time bug?

Hello
I played a blitz game, but the time of my opponent increased (I guess as a 5+3 instead of a 5). Maybe I made a mistake and played a 5+3, but I don't think so. It is my last game if somebody wants to check.

(I don't mind for the defeat, just try to inform if maybe a bug etc.)

long live lichess!!

thanks

Hi,

Can you show us the game? The answer should be there

Last game you played was 5+0.Time can be increased only if opponent has some lag,which gets compensated by adding time to their clock.

Oh! Thanks risky chess! it is correct, but surprising of course.
