Prior to 1.14 one used to be able to use mcfunctions to summon an entity (armor_stand, area_effect_cloud, etc) [edit] and then move it [/edit] into even a currently unloaded chunk, and then teleport the player to that entity's coordinates, in order to teleport a player to far away places (like for adventure maps and such) based on scoreboard stored coordinates.

With the release of 1.14, all such functions are broken.

 Example:

summon armor_stand ~ ~ ~ {NoGravity:1b,Invulnerable:1b,PersistenceRequired:1b,CustomName:"{\"text\":\"teleport\"}"}

execute as @s at @s store result entity @e[name=teleport,limit=1] Pos[0] double 1 run scoreboard players get @e[tag=Clerk,limit=1] gat_1gold2x

execute as @s at @s store result entity @e[name=teleport,limit=1] Pos[1] double 1 run scoreboard players get @e[tag=Clerk,limit=1] gat_1gold2y

execute as @s at @s store result entity @e[name=teleport,limit=1] Pos[2] double 1 run scoreboard players get @e[tag=Clerk,limit=1] gat_1gold2z

tp @s @e[name=teleport,limit=1]

kill @e[name=teleport]

This will have massive negative repercussions on any and all adventure maps / minigames / worlds where it is necessary to move the player around as they progress through the experience based on scoreboard-tracked coordinates.
