Possible bug with unit level

Last TFT game I played I encountered a possible weird and very serious bug

Shortly after the raptor round all my 2 star units seemed to be treated as 1 star by the game. If you right clicked on each of them it was still displaying them as 2 star but the bar in the right with the damage dealt breakdown would only show all of them as 1 star units.

It did appear as if they were playing as the 1 star versions as well as from then in they did significantly reduced damage and didn’t last anywhere near as long.

This lasted all the way until I got knocked out and before anyone asks no every opponent did not have cursed blade or whatever it’s calked that shrinks units.
