When Rider Forgets How to Write Assembly Definitions: My Day-Long Fight With UnityAtoms

A developer working on the tactical space-combat game The Weight of One: The Jovarko Incident encountered a significant issue with JetBrains Rider. While implementing a selection system across modules like Core.asmdef and Systems.asmdef, the Alt+Enter shortcut stopped updating .asmdef files. This occurred after adding UnityAtoms via the Package Manager to utilize AtomEvent and AtomValueList. The developer spent an entire day diagnosing why the IDE ceased writing dependencies to the assembly definition files.
