SentinelCollaideEnterimI know how it works, but why thoughCollaide[...]answering this a day late: that's always been in the game because the game's definition of "self-inflicted blast damage" is more specifically "self-inflicted blast damage that doesn't damage any other players". blast jumps that splash damage enemy players even a little bit don't get the self-inflicted damage reduction for that reason.
Along with that bug, I would also like to know why soldiers with gunboats deal 80 damage to themselves if they also hit an enemy (even if they perform a rocket-jump, which are said to have reduced self-inflicted damage according to the item's description)
Because it would be kinda retarded to point blank someone for 112 and fly away to safety while only taking 18 yourself
I'm mostly think about the scout encounter indoors or when they run into you to force you to do 80dmg to yourself
