Particles direction is bugged for projectiles

When i write a line like that. - effect:particles{particle=reddust;amount=1;hS=0;vS=0;yOffset=0.1;speed=0;sideOffset=-0.2;forwardOffset=0.8;size=0.8;color=#c44d00;repeat=5;repeatInterval=5} @ProjectileForward{f=1} in 5.3 version the offset was relative to projectile direction. With latest dev version, the particle goes in Minecraft's Axis direction, even if i set @ProjectileForward as target... Anyway, in past version, it was good also a simple @origin

Please fix this problem. Priority level: Very High, because it's going to destroy all projectiles created until now (except simple particles without offsets or shape)
