Steps to replicate:

I put an item request for a construction robot into a roboport and attempted to construct the item request with a spidertron.
When this didn't work I also tested regular chests and the player character's personal roboports, which all have this issue.
(Note the roboport was in an outpost network so ...

(Although it makes sense for changing speed modules, which do decrease quality, to reset the ...

I'm noticing this as well in 2.0.15 on inserter quality changes (and presumably all the previously mentioned things as well)
and since this post already exists I'll just add a comment to it.
A few things I noticed:

This means flamethower turrets now need power which is something they previously didn't

This makes me think biters should mostly follow these paths when pathfinding
I think there's already a system where they follow previous biter trails (to save performance when pathfinding) so maybe these forest trails could be an extension of ...
