I have tried the mare all read button and clicking every individual item in the guidebook, and for a time it works. Eventually though when I pull up the guidebook everything will be highlighted again.
Thank you for continuing to upvote and comment on this issue.
To confirm, those who are still experiencing the Guidebook Items appearing as New, does this only happen after logging out and back in? Or do the entries become New again at any other point?
Responding to the dev question:
Every time the realm is loaded, the bug happens!
Even if the realm is already visited, like the home. The only exception is the minor portal events in biomes, in there the guidebook not mark everything as new again...
Every time I load a page either new realm or into the game it makes all my building blueprints new again.
Perhaps a simple QoL solution to this would be to remove the 'new' section and have a small 'new' icon placed beside the item in the categorized list in the same location as when players 'mark' a recipe for crafting?
It should be noted that this bug still occurs in v0.3.1, even though the v0.3.1 patch said it was supposed to have fixed this.
