MC-104141Structure Block Loads Piston Heads Incorrectly
Save a Structure with a piston facing north and a repeater which powers it directly from the west side. When you load it, you will get a piston without a piston head.
Loading the Structure a second time (when you have a piston or a repeater at the same place) will place the piston head correctly.
Rotating or mirroring the structure has no effect.

I have detailed instructions and a small structure file that allows the world to be created from scratch on demand.
Version 1.12.2:
Create a new world in Creative mode with the seed 1.
Copy the structure file "g12.nbt" into the "structures" folder of the world save.
Run the following commands:
/gamerule doDaylightCycle false
/gamerule doWeatherCycle false
/gamerule commandBlockOutput false
/time set 6000
/setblock 160 100 256 minecraft:structure_block
Go to the structure block (it will be nearby in the air) and load the structure "g12" twice in quick succession. (Loading it twice is necessary to work around MC-104141. If this is not done, the piston heads will be missing on the extended pistons and the contraption will malfunction.)
Stand in mid-air above the oak log on the platform.
Press the red button on the right. Three redstone blocks will disappear, arming the contraption.
Press the green bottom on the left. This will start generating chunks by teleporting the player around the map. This will take 10 to 15 minutes to complete.
When the contraption is finished, the player will be floating above the oak log.
(If the player teleports once more, the player can be returned to the device with /teleport @p ~-256 103 ~.)
Save the game.
Version 1.13-pre6:
Make sure the launcher is configured to display the game log.
Load the save game created previously in 1.12.2.
Alter the commands in the two command blocks marked with blue concrete by changing the first part of the teleport command from "execute @p ~ ~ ~" to "execute at @p run".
(If the player teleported after the end of terrain generation, check the middle pair of hoppers for stray redstone dust and move the smaller stack to the other hopper.)
Stand in mid-air above the oak log on the platform.
Press the green bottom on the left. This will start converting chunks by teleporting the player around the map.
Watch the log - the enum errors may occur.

Is this still an issue in the latest snapshot 16w44a? If so please update the affected versions.
This is an automated comment on any open or reopened issue with out-of-date affected versions.
Can reproduce (see 2016-11-06_17.27.24.png)
Does this problem still affect 1.11.2?
Reproduced in 1.12.2 using the structure "g12" (attached as structures.zip
)
Seems to be fixed. 2018-09-19_17.08.44.png
