Null Pointer Exception with animals in a basement

[macas1]

Version: [42.5.1]

Mode: [Singleplayer]

Server settings: [N/A]

Mods: [None]

Save: [Old Save]

 

Notes:

I currently have a save with pigs in a basement. When loading this save, after a short but random time, it will crash.
I'm not sure if it's related, but I also get an error when trying to create animal zones down there.

I have uploaded videos and stack traces for both scenarios.

The basement I have gotten the crash in is located at the northern Rosewood gas station (X: 8178, Y: 11268, Z: -1)

I have save games just before and after the crash if they are needed but they are too big to upload here.

Thank you.

The first error is because your some pigs are starving, and the tryAndGetGrassFloor method detects a null square.

Thank you, this does appear to be the same bug causing the crash issue. In my example, the pigs are well fed and have access to food and water in the basement, so it seems they still look for grass floors regardless.
