drama_node aka phone calls

Okay, so right off of the top, I'll say that you should be sure to always use the hash generator feature to generate instance & tuning IDs. Usually if you change the name of an extracted in-game tuning file (<creatorName>:<filename> format seems pretty common for this), Sims 4 Studio will auto-update the tuning ID and the instance number of the item. Type number should remain the same, but group needs to be manually changed to 80000000 (to indicate it's a custom item and limit chance of accidental override of in-game resources). You may have already known this, but others might not, so I just wanted to clarify that.

One of the things about drama nodes is that they have to be scheduled at some point or another. The resource you're overriding is already referenced in another tuning file somewhere, and is scheduled to run after a certain action is taken in-game. Once you are no longer overriding that resource, this link breaks. So you have to find somewhere appropriate to reference this tuning file, and schedule the drama node. The best way to understand how to do this is to actually see how the game does this with another node.

So, lets take, for example, the "happy text" drama node that happens when you send a happy text to a sim, and then they call you back and invite you out somewhere. This is triggered from the interaction tuning for "phone_Text_Happy" (127149) inside of its "basic_content":

<V n="basic_content" t="flexible_length">
<U n="flexible_length">
<L n="conditional_actions">
<V t="list_reference"><!-- irrelevant stuff truncated--></V>
<V t="literal">
<U n="literal">
<L n="conditions"><!-- more irrelevant stuff removed--></L>
<E n="interaction_action">EXIT_NATURALLY</E>
<L n="loot_actions">
<T>100674<!--Rel_Gain_Small_Text--></T>
<T>24009<!--loot_Buff_Phone_SendText_Success--></T>
<T>100673<!--Loot_Buff_SentText_Cooldown--></T>
<T>127257<!--loot_DramaNode_HappyText--></T> <!-- THIS is what we're interested in -->
</L>
</U>
</V>
</L>...

If you open up that LootAction, you'll see that it links to the drama node to schedule, and contains a test to determine what sims are eligible to receive this loot.

So, depending on what you want your drama node to be triggered in response to, you'll link to its LootAction in different places. I would take a look at various interactions and see how they handle loots. Looks like OP is using the old fitness stuff earbuds dialog as a template... I don't know where that drama node is scheduled, so if they want to trigger theirs at the same time, they'll need to dig around a bit and see if they can find that. It might be tricky, as I think that feature was removed in a recent update (I sure haven't been getting that dialog anymore these days).

Edit to add that this:
is really weird and I can't think of a good explanation as to why that would be happening/still working...
