These bugs happened when i was coaching a friends game. as soon as the map loaded, all i could see was my friends team, but no normal highlighted vision, similar to how blood seeker can see targets with very low health.
whenever they would cast spells, it would sometimes disappear for a short amount of time, in a short radius. I hope that this is helpful, thank you for your time.


P.S if theres any more info i can try and provide please ask here or message me
