I set a hopper timer with a delay set using blockdata and it only affected my game once in every 3 times approx
/particle mobappearance ~ ~ ~ 1 1 1 1 @p
Multiple crashes, not every time mobapearance appears, 1/3 chance of crash, opening command block with mobappearance particle causes crash, 1/3 chance of crash when opening or seeing a mobappearance particle
Setting the speed of the particle doesnt affect how it displays, is it possible setting a speed with this particle causes crash?
