yeah what are some of like the biggest challenges that you had when when working on the drones was there anything that like really threw a wrench in the works or was it like overall kind of just smooth sailing as you develop them, yeah I mean there's there's a lot of challenges with it, because it's such a big feature, you basically need to keep in mind everything that can go wrong as you're working on it so for example, what happens if you dismantle all the stations in the world and then you just have your drone stuck in the air what happens if you dismantle a drone which is docked at a station and all kinds of things like that and even just like having two drones arrive at the same station at the same time what should happen in that case so it's all about like those weird edge cases I guess yeah exactly and you need to keep them all in mind at all times during development as well right right sounds rough so I guess it was it was it was that and and the, pathing I guess was the other biggest thing yeah and just making them work in general, so there's a lot of a lot of moving parts to this, this feature nice nice must feel good to have got it all together oh yeah for sure yeah I see like a lot of people wondering if they can if they'll be able
