5.5e still not fully coded properly

I find it baffling how the 5.5e rules have been out for over a year and a half, and there are still many core rule features that D&D Beyond is coded to work differently than what the books say:

Warlock invocations not letting you choose cantrips other than Eldritch Blast, Wizard's Abjuration Savant adding spells as always prepared instead of to the spellbook (probably the same with the other subclasses too, but I haven't tested them myself), Spells that deal different damage amounts (like Toll the Dead and Ice Knife) only giving one roll option while versitle weapons give you both rolling options, magic item charges not refreshing on long rests, some bonus/actions not listed in the right spots on the Actions tab, always prepared spells still being able to be chosen when preparing spells (leading to picking the same spell twice if you're not paying attention), not being able to expend Hit Dice when not taking a short rest (even though the Healer feat and Arcane Vigor let you do that), and many, many more. 

At this point, rather than fixing issues as people find and complain about them, it would probably be better for them to manually go through every rule to make sure it's working as intended.

All these things are a result of the current character builder having hard system limitations and is the reason why they're working on a rebuild of the builder. They've said once the rebuild is complete, they'll not only be able to better support existing features, but will be future proofed in a more robust way

That actually makes a lot of sense. I'm not sure how I didn't realise that rebuilding the character builder included rebuilding the backend codes and not just the visuals.

the news about the big backend rebuild is, to me, the most exciting. i'm curious to know what features were difficult or even an impossibility to implement before that we can expect to work seamlessly through the new character builder. can you name some specific pain points you want to eliminate?

WOTC_BrianPerry: 

I asked the team to give me a list of their top pain points and got quite the list back. Here are just a few things that are near impossible to implement today that will be possible with the rebuild.

• Monsters or Stat Blocks that scale with your character level (for example, the Draconic Spirit from the Summon Dragon spell, or sidekicks from Tasha's Cauldron of Everything)
• Using Hit Dice as an expendable resource (like with the Durable feat)
• Giving Magic Items actions. For example, today, you can't roll the additional Fire damage for a Flame Tongue weapon
• Having conditions work in the character sheet
• A lot of UX-based things, such as being able to expend a spell slot to recharge a feature
• The Aberrant Mind and Clockwork Soul's level 1 feature from Tasha's Cauldron of Everything
• Charms/Blessings
• Content that meaningfully deviate from the D&D 5E core rules in a non-trivial way
• Minimum dice values (like with a Rogue's Reliable Talent feature)
• Wider Eldritch Invocation support (like being able to target spells that aren't Eldritch Blast with Agonizing Blast*)*

The list goes on. I’m stopping here to keep it from becoming a novel.
