For example, if you do this on some mob: - totem{ch=0;i=20;md=80;bulletType=DISPLAY;material=yellow_stained_glass;scale=2,2,2;yo=0.6} @self ~onTimer:80 The object initially appears where it should, but then very quickly shifts to z=+2.
If you try to work around the bug by using a projectile like that
SpiderMother_Egg_Tiny: ... LevelModifiers: Health: 1 Damage: 0 Skills: - projectile{type=NORMAL;velocity=0;bullettype=DISPLAY;bulletmaterial=pearlescent_froglight;bulletscale=0.4,0.6,0.4;hitself=false;hittargetonly=true;hitnonplayers=false;hp=false;maxduration=120;forwardoffset=0} @self ~onSpawn - projectile{type=NORMAL;velocity=0;bullettype=DISPLAY;bulletmaterial=gray_stained_glass;bulletscale=0.5,0.7,0.5;hitself=false;hittargetonly=true;hitnonplayers=false;hp=false;maxduration=120;forwardoffset=0} @self ~onSpawn
the bug still persists. But for some reason, if you spawn it from an egg, everything works fine, but when another mob spawns this mob, the display bug reappears.
