I sent resources to Bestiary from planet 'A'. Later I requested (from Planet 'A') that those resources be returned.
Instead of the resources being returned to the originating source (Planet 'A'), they were sent to a passing Space Station, that happened to be closer to the Bestiary.
My Space Station was not equipped to either hold or transfer the quantity of resources it received.
Hopefully, this is actually a programming oversight / error and will be corrected shortly and not a permanent change in procedure.

Bug or procedure change - I'd like to know.
