Bugs. The remains of destroyed buildings do not disappear

[Ziomek24]

The remains of destroyed buildings do not disappear and the area where the Bitter lairs were does not turn into grass, for example.

Thanks for the report. That is intended and was mentioned in the changelog.

Sorry to bother, but is there a reason building remnants are set to never expire? I feel that would be a visual issue for players who don't want them there anymore. I was just wondering what the logic was for keeping them.

[Rseding91]

They are removed when you build over them. They are left there as a reminder to what happened in the past. If you start building over them then they go away.

Yes, I was aware of that, building over just to remove them can just be a hassle for some players, but the reasoning to leave them in as a reminder makes perfect sense. Thanks for the response!

Each Remnant is only removed, if you place a single entity over all of it. If you place for example belts or assemblers perfectly covering an entire area and then deconstruct them again, there are still remnants left after you remove it.

Killing a demolisher creates remnants of every building build under its final position, even with construction bots unlocked. It is an annoying eye sore and there is no easy way to remove it. Could we at least get a "building remnants" optional filter on deconstruction planners?

That sounds like you’re using mods.

Only if you count space age as a mod.

Attached is a demo save for the first paragraph.
There are gun turret remnants covered by belts and a mix of other entitites. But the remnatns below it still exist and are not removed on placing entities over it, unless you cover the 2x2 square with a single entity.

The second paragraph is also true in space age. Happens frequently when using gun turrets against a demolisher. demon2 shows the result after a demolisher was killed by gun turrets. you can clearly see some remnants under it without the gun turret ghost on top of it.

So it turns out I was wrong. For some reason, when the new remnants were created whoever created them did not give them any collision box. That means they only ever go away when something is built directly on their center. They should have the same collision box as the entity they represent so they go away when something is built over them.

I'd like the disappear time to be configurable in Options. Don't want them to stay forever to clog savegame size, but allowing to set some reasonable time like few hours would be the nice implrovement.
