This was a fun unintended bug that created some avatars like graelyths kerbal avatar, but it is pretty depressing to see that it was removed without simply just fixing the colliding so people couldn't fly outside, but instead, shows that removing it just ruined the fun and creativity on this social sandbox game which is to expand creativity, but with recent updates, it shows that the devs are completely distant from the community and has been getting worse in 2019 where an unintended bug could become a useful tool for making newer avatars with proper tweaking to fix it to collide with colliders as intended.
We like to see the fun expand, not get limited because someone found a cool bug that could become a badass feature for pc users. I get sick of stuff getting limited or removed because it doesn't work with quest.
