I believe there was an intention in patch v.0.9.15 to add helpful information to each module installed by specifying the ship it is installed on when you look at it in the warehouse. However the placeholder for the ship name is not being filled in so the text displays “Installed on $ship$”.
Adding a screenshot of the bug.
Well, they must be installed in Premium $hips. HEHEHHEHEHE
Thanks for reporting. The bug has been forwarded!
