Place an Effects module - IR grenade on a map. Name it. Place a player, set time to night. Create a trigger with init deletevehicle vehiclename. I also tried setdamage vehiclename - not that we would expect this method to work.
There isn't any means to remove the object once created. Other triggerable effects can be removed via the deletevehicle method. Although I have only checked the Tracers effect and can confirm that this effect can be 'switched off'. Other module effects may have also been broken assuming this is a recent issue. Can't find other related tickets.
