Before my problem is setType method (https://www.spigotmc.org/threads/block-settype-material-doesnt-work-in-1-14-4-unloaded-chunk.393474/) then i realized i can't change anything in chunk when i am not at chunk. I also spawned armorstand to test it
armorStand = (ArmorStand) location.getWorld().spawnEntity(location, EntityType.ARMOR_STAND);
if(!armorStand.isValid() || armorStand.isDead())...
it shows armor stand is valid and is not dead but like setType of block it doesn't appear. Also tried in 1.13 it doesn't work. But in 1.8.8-1.12.2 it works.
