To reproduce the bug: Stand by the Exchange. Now open the main DOff window. Open and select your Department Heads view, then click any of them to view their departmental assignment list. Click an assignment to view its requirements. Now click to open the Exhange.
Bug: now the Doff window will reset to the main assignments view (for current sector) instead of remaining set to whichever departmental assignment you had selected.
This is annoying because maybe you are tryin to get the rare commodities or Doff that your departmental assignment requires and you will now have to navigate all the way back to that screen again since the Doff assignments view has reset to sector.
You may now commence posting your inane one-liners just to get your post counts higher.
