whenever copying an inserter with long handed pick up, drop, or near side of belt on with a blueprint, if you turn the settings off and keep enable reach overrides on, the inserter doesnt save and goes back to normal when placed(haven't tested with normal bots, but personal roboport bots have shown to). if enable reach overrides is turned off, this does not happen. is this intended as i don't remember this being a thing, sorry if so. this also works vice versa, if you copy a normal inserter into a blueprint, and then have reach overrides on with a setting applied, they are overriden to have the new settings on them

No, that doesn't sound intended. If you copy and paste an inserter, nothing should change. I'll investigate and let you know what I find.

if needed i can try to get a gif or video of what i mean (was having trouble wording it), but thanks ^^

I have the same problem, inserters take and drop positions doesn't copy in blueprints, you have to manually configure them after blueprint is pasted on the ground
