On the surface this looks a bit like #2590, but that issue was fixed in Galileo. We would need a save and [logs](https://github.com/mockingbirdnest/Principia/wiki/Installing,-reporting-bugs,-and-frequently-asked-questions#reporting-bugs) to investigate.

@fictionles: The behaviour you are describing (flight plan window shrinking to size 0) is a bug. We'll need steps to reproduce it (i.e., the sequence of actions that lead to...

@michaelorella: I could see adding a functionality to delete the entire flight plan. It's not in the current UI to make sure that users don't click it by mistake and...

Closing as the rotating-pulsating frame introduced in [ابن الهيثم](https://github.com/mockingbirdnest/Principia/wiki/Change-Log#%D8%A7%D8%A8%D9%86-%D8%A7%D9%84%D9%87%D9%8A%D8%AB%D9%85) addresses this issue properly.

Arenas don't work well with STL or absl containers, so nothing left to do here.

This is still a thing because to be honest I never looked into it. A problem with "hack gravity" falls into the category "Doctor, it hurts when I do this!"....

Closing as we have not heard of this bug after #3349.

Oh I am so glad that my misguided comment made you react because I was literally just reading your [guide on profiling the C# side of the mod](https://gist.github.com/gotmachine/d973adcb9ae413386291170fa346d043) and to...

In the end, we decided to compute the impact properly, taking the terrain into account (and not assuming that planets are spheres). For the record, it's not practical to find...

Also unify the operators in `fixed_arrays` and `unbounded_arrays` to avoid having each implementation twice.
