I have the issue that when I use the zipline to travel to a building site, all my personal robots come out while I'm still on the zipline. And once I get off, they no longer belong to me and fly home to the nearest roboport network.

Would it be possible to just disable personal roboports and personal logistic while on the zipline? This would remove any issues with robots leaving or attempting to deliver stuff while I'm just passing through at nuclear-powered high speed.

Do you mean to always have the roboport disabled when getting on the zipline? Right now it keeps whatever setting you have on foot, but I could add a mod setting to always set it to off when using the zipline

I don't know if the original behavior could also be considered a bug:

When I take the zipline to some place where my personal bots will try to build something, they will leave my character while I'm still on the zipline and make their way to the blueprint spot.

As soon as my character leaves the zipline, these bots no longer belong to me, my personal bot count has been reduced in the inventory. The bots will then abandon the building task and fly to another roboport network far away.

The same thing happens for personal logistic requests:

When I take the zipline to my main base and I have let's say 100 missing power poles that are requested, the main base bots will come out of the roboports and take the poles they intend to deliver to me.

As soon as I get off the zipline, these bots take the power poles they're holding to storage chests and another set of bots is activated to deliver the poles.

It's as if the character on the zipline and the character on the ground are two disjoint entities?

All this funky behavior can be prevented by disabling the personal roboport (to prevent my bots leaving) and personal logistigs (to prevent main base bots from attempting to deliver) before I go on the zipline. But I sometimes forget to do so.

Behind the scenes the Zipline character is indeed a separate copy, one that's immune to collision so that you don't get hit by trains while on the Zipline. I haven't found a way in the modding tools to "reassign" the bots to the copy. Maybe I can ask some more experienced modders if that's a thing. But even then, I guess that doesn't help when you zip past some blueprint ghosts super fast lmao
