You seem to have desynced from the fights. Clearing cache and flushing DNS should help:

1. Clear the game cache (cog icon in the top right > clear up system)

2. Flush the DNS cache (open ‘command prompt’ on the PC and type ipconfig /flushdns and hit enter)

3. Reboot the PC (to be extra sure, reboot the modem / router too)

All members need to do this for 3v3.
