[TF2] Merasmus' ranged spell attack on Ghost Fort does not ignite players because of Truce
ever since the november 3rd, 2015 patch, truce was added to make fighting monoculus and merasmus less annoying, but it's also come with it's own bugs, one of these bugs includes merasmus not being able to ignite players anymore, they'll still play the "on fire" voicelines and their ragdolls will get the firetile texture when killed by merasmus' ranged spell attack (the one where he stands still and raises his staff in the air, igniting and sending any player hit by it flying into the air.) but will not be ignited at all or take afterburn damage from the attack.
Lol prehaps thoses bugs are why the bosses became kinda easy to kill, if they can't kill us then we can kill them
