Biter Dissapearing

[Coffee Daemon]

So in my (admittedly well modded) playthrough I befriended a biter. He is currently in an area walled off with blue belt in a circle and radars around to keep aggro for him. He has been there for some time and just disappeared.

Do biters despawn after a time? Cause I saw him despawn infront of me. No corpse, and no reaction when I equip PLD.

I have a save just before he dissapears. Watching from map view and just vanishes.
EDIT: Reproduceable, always goes in the same corner too, may be coincidence due to belts.

This is the first time I've ever seen the lack of a bug to be considered a bug

Anyway, I suspect maybe they have a timeout despawn to make sure they don't get stuck somewhere in the world. Though I can't think of how that would happen.

Yes, biters that can't path for extended periods of time are simply deleted so they don't waste CPU power.

What classes as pathing for this scenario then? Just wondering if I can get around it for a single biter.

Also, RIP Jeff. His houdini act was superb.

I would like to request that this be considered a bug, as it affects non-biter units as well. I had a couple hundred robotic attack drones (Bob's Warfare mod) disappear on me under similar circumstances, although they were mostly milling about open fields. Which actually is kinda weird, if it's an inability to path that makes them despawn, but.

I'm new to Factorio modding, though it looked like all entities the player makes are normally marked with a "player-creation" tag. Perhaps the despawn check could be ignored if it sees that tag on the unit?

If someone knows a way how to prevent a certain biter from despawning, please let me know!
Because i would love if the "pet" biter script i made was working like it was intended ._.

You'd have to post the save. There's literally nothing I can do with a video.
