Iron golems do not spawn in center of village

See MC-122538

MC-122538 relates to a single village iron farm.

This is for Multi village ,Self Stacking farms, which a majority of online servers use.

Does this happen when the world is upgraded from 1.12.2 to the latest 1.13-pre6? If so, can you attach the world from 1.12.2 here so we can reproduce the issue?

This happens when upgrading from any version from 1.8 up.

The Iron tower works in all versions from 1.8 up to 1.12.2 download from here http://www.mediafire.com/file/nqa9iixl7l7ktnt/Layered+Iron+Farm+1_8+v5+FINAL.zip

You can also download any of Tango Tek's iron farms or even iron farms from GruvaGuy

Note :  You must restart the iron farms to create pre6 village.dat info ( the restart button for the iron tower is in the basement of the farm) as you would not have this info if building from scratch in creative ( the downloaded farms will look as they are working first time but they will be using the old dat that will change )

Still broken in 1.13-Pre7

Still happens with me in 30b

Broken in 18w30b

same farm: 30a and 30b running at same time

Left : 30a golems spawn in right place. Right :30b golems spawn again in wrong place.

Please Reopen, Self Stacking Iron Farms, all were working in 30a but are now broken again in 30b.

Can I please have independent confirmation on other Self Stacking Iron Farms. from 30a and 30b

Derek Dalton really? I tested another self-stacking farm, the Iron Casster by GruvaGuy, in 18w30b and it worked fine. I also tested the Iron Stream by Eta740 (after making a few small tweaks to the piston validation system) and it worked too. Golems may be spawning all over the place while the farm is moving villages, because of a bug where golems can spawn in air: MC-134889, but other than that it worked for me. What you're describing may be a problem that is specific only to the Iron Towers design...

TY. Will keep an eye on MC-134889 as this must be the problem.
