My server run on NukkitX.The last released version of NukkitX had updated the particles'network IDs provided by PocketMine.But particles like DustParticle didn't show.And some particles can be shown on device only show part of the server sent.(like HappyVillager particle,spawn 5 particle line only show one,and every of the particle packet is acturally send to player).The problem appear since MCBE1.11.x.I think it may be NukkitX issue at begin but it may be Minecraft issue after I failed in testing spawn particle by commandblock in my own world.
Wish close the issue fast.My server had lots of particle effect but now it almost all disappeard
