Wizard Spell Mastery Not Prepared Properly

I believe the 18th level spell mastery isn't preparing 2nd level spells properly, but perhaps I'm not seeing something? 

This appears to only affect the 2024 wizard. I've added Mirror Image as my second level spell mastery spell and it does not appear in my spell list or prepared in any way. On the 2014 wizard I made, it does. I've tried this with blindness deafness as well and it does the same.

I'm experiencing something similar! Although the 2024 class feature was updated to always have your Lv. 1 and Lv. 2 Spell Mastery spells prepared (you used to have to select prepared spells for Spell Mastery in 2014), they don't appear in my character sheet at all until I do prepare them (deducting them unnecessarily from my total spells prepared). When I prepare them, they show as castable with slots AND as "At Will." It seems like the feature coding wasn't quite changed to reflect the new verbiage in the 2024 PHB.

Same here, and still no fix or even comment from DnDB.

2026 and this is still a problem.

Yes this still a problem

For anyone wondering, Yes it is STILL a problem

Is there only one dude in the WotC basement managing this website asking where his stapler went?  This is either a result of sheer incompetence or total apathy.  It’s bad enough some idiot at WotC changed 18th level spell mastery (18th LEVEL!!!!) so wizards can’t use a bonus action or reaction spell, but then to break the feature and no longer support it on the WotC website is criminal.

 The system cannot do this until the site revamp.

This has been said on all 3 official comms(Discord, Reddit & the forums).

It's not a matter of competence or conspiracy.

Well then the developers shouldn't have changed it.  Spell Mastery works fine with 2014 rules.  If they couldn't support it they shouldn't have changed it.  It's a stupid change to make to 18TH LEVEL CHARACTERS anyway.
