For some reason the damage numbers kept ticking and following the players hit by the fire after the effect ended. The damage numbers allowed them to be tracked through walls and did not stop ticking until they died. The players affected said the "on fire" hud effect kept showing on their screens.
🔥🔥🔥 Here is a clip of what happened: https://clips.twitch.tv/MoistPreciousCardMau5-C_nNA6cFg3U_X67d
I was teaching my friends how to play in private 2v2 matches on Japan server. One set of friends was playing from Taiwan and the other set was playing from Japan. This happened atleast twice randomly, but we could not recreate it yet.
