Thank you for making this wonderful mod!

There seems to be a replicable issue with this mod, and the crash-dialogue suggested that I report this information to the mod author.

The mod portal's information regarding this mod's update history would seem to imply that this is an actively supported mod. However, there have been no recent replies to recently-posted comments in either this thread, or on the discussions page of this mod's portal listing. Can someone please confirm that my info is being received? Thanks!

Info about the crash -- this crash seems to be triggered when attempting to click this mod's UI button with an inventory-blueprint-book in cursor. Individual blueprint-pages, whether in inventory or from the blueprint-library, does not seem to trigger this crash. Note that when attempting to click the UI button with a library-blueprint-book, this crash does not take place AND no mod-behavior takes place (i.e., it's a wasted click, albeit an inert one).
