[2.0.23] Can't destroy biter spawner

[SHADOW13]

So there are some biter spawners that I previously captured, away from the base
Since then I developed technology to build those so no longer needed those, left them alone and they reverted to "wild" spawners

Now, I am away from the planet but wanted to get rid of those spawners

So I drive remotely my spidertron and .... NOTHING
Spidertron does not target previously caught biter spawners - rockets or personal lasers.
Can't even kill them manually with space.

While I understand there might be need for recapturing them, completely preventing Spidertron (or other weapons) from attacking or destroying those spawners is a wrong way to do it.
Either player should build in a way not to destroy those, or just capture new ones, like they go out and venture to claim new resource patches.
