Constructing pipe/rail/wire behind wide hydroponic farm will damage this WHF

I tried reproducing this issue but I have not been able to make it happen, do you have any more details you can provide that could help narrow down the cause?

I didn't notice what happened exactly, maybe it's probabilistic

I experienced this twice today as well. It occurred after installing a pipe in the left most tile of the wide hydroponic farm both times. First time the dupes repaired the farm it allowed water to pass through the tile as if it was still broken. Second time the tile had an 'infinite' repair job, the dupes would be constantly repairing the tile with no progress being done. Reloading the game corrected the issue, I could even install pipe behind the farm tile without further issue.

I was able to duplicate it again by building a wide hydroponics farm over existing tiles. Building pipe on either side of the intake broke the farm and it did the ‘infinite’ repair task again. Reloading the game fixed it again.

There is an instance where they fail. Not sure how they could fail when you first built them though but fixing a broken wide hydroponic farm doesn't bring back the "solid" of it until you reload the game.

wide tile.sav Let wide farms break. Then let the dupe out to fix them. Check if the fixed wide farm is solid.

I have managed to reproduce this consistently on my older save file

1) Create hydroponic farm
2) Plan to build pipes
3) Dig errand gets generated

Dehydrated 15.sav

EDIT: This is probably related to backwalls, there are two backwalls underneath the tiles

Outdated information

I did some more testing, this is not related to the backwalls, dig errand gets generated for the outer tiles if they were originally player made tiles. Replacing two player made tiles with the hydroponic farm generates only one dig errand, air tile won't have the dig errand. I have stumbled upon a bit strange behavior - replacing one player made tile with the hydroponic farm is not possible unless player made tile is in the middle of the hydroponic farm.

Changed Status to Fixed

Thanks! the video helped a lot!
