Nether Portals spawning algorithm changed breaking some very old farm designs

In my 1.7.9 world I built a massive gold farm using Nether portal whose floor was removed. I plan to update my save soon so I’m testing if everything works fine in a copy of the world. While doing so, I discovered that Zombie Pigmen didn’t spawn anymore on this farm. This happens from snapshot 19w12b onwards.

After researching the latest version, I noticed that the algorithm that looks for a floor to spawn the Zombie Pigmen (at NetherPortalBlock.randomTick) keeps iterating only while it finds NetherPortalBlock instead of non-solid blocks as it used to be. Reverting this change does not damage nor benefit the standard game, given that usually there are no portals without floor, but it saves these extremely uncommon farms. I spent hundreds of hours building the farm, I beg you to change this back.

Hello, thank you for reviewing my post.

Would it be posible to at least keep the report as private since I consider part of the information provided as "personal information"?
The reason I submitted it as private is because I'm a content creator and the reasoning behind the report contains spoilers of the content I've been preparing for years now.

On the other hand, what I'm asking for is to revert a very specific change of the behaviour of an already existing feature since way back, when portals were added to the game. I don't see it as a feature request or suggestion by the same logic as, if Zombified Piglins stopped spawning on obsidian in the next release, it would be a unintended change caused by code refactoring. And, as I argumented in the report, being that uncommon, this case is probably the same as the example.

This issue has been close as invalid. It's unlikely moderators will see any further comments. It's best to follow the suggestions provided.

 

Portals with the frame blocks removed are not a supported feature.
