Blueprint books dont close correctly

[Bravis Tickle]

Noticed today that once you have opened a blueprint book once after logging in the Trade Terminal think its always open and gives the following error: [System]: Containers need to be closed before they can be traded.
I haven't been crafting so I am not sure if this might be a problem elsewhere when using blueprint books or blueprints.
Tested this on different servers around Calypso and same problem everywhere.

The bug is old as heavens, thought they fixed it as I successfully traded a book and its blueprints with a friend not long ago (so the book had to be opened and bps extracted before trade). Apparently it affects only tt.
