When I remove a room from the ship, and re-add it - there seems to be a feature which (sometimes) restores the previously placed modules to that room.
However: When I restart the client- the modules are never there. I can only assume this is a bug in that the modules seem to have only been visually restored. It doesn't seem they have been actually properly replaced.
I don't think the savy soda is invested in fixing modules bugs, however, thought I'd add this to the list...!
(Appreciate everything you do in other ways SS team!)
