I noticed a lot of duplicate entries in the logs

I assume you have active requests for a spider-tron. I did not know that was possible, which is why they are unsupported.
I will try adding support when possible, until then the spidertrons are ignored by the scanner.
Everything else should work as usual.

I think this is a reaction to this mod https://mods.factorio.com/mod/Constructron-Continued
