I owned every dlc for The Sims 4 except for Courtyard Oasis and Modern Menswear, since the transfer happened I am missing all my Kits in addition to Cottage Living, High School Years, Werewolves, and My Wedding Stories. As you can imagine that is a lot of money spent and a lot of saves I now can't access. None of these were mentioned as being a problem by the Support Expert I spoke to, although they did mention The Sims 3 and The Sims Medieval as potentially not transferring correctly (they both did). I've read through the disclaimer four or five times now and nothing in it mentions Kits or any of the other dlc as not being available for transfer. I've tried clearing the cache and it hasn't worked, but none of the other advisors have been able to help me.

For reference, here is the disclaimer:

We can only transfer all Origin/the EA app PC games that are in the account. We can’t transfer only one or a few games.
We do not transfer duplicate games in order to preserve their accounts and games integrity.

We can’t transfer EA Play Memberships / Third-Party Games.

We can’t transfer SWTOR because a player’s SWTOR account is connected to the EA Account. If we remove the SWTOR game from the original EA Account, game data will be lost, and the game will be unplayable.

We do not transfer Apex Legends and the latest version of FIFA in order to preserve accounts and games integrity. We recommend that the EA Account which has SWTOR, Apex Legends, any Third-Party games, the latest released version of FIFA and/or an active EA Play membership to be the primary. However, if the player decides otherwise, they will lose all this content.

In order to merge your EA Accounts, I’ll need to remove your games from the old EA Account so we can add them to the primary EA Account. When I do this, you will lose the progress, saved data, and stats from your games saved online on EA servers to your old EA Account. This includes:

any content you’ve saved to the cloud
any online and multiplayer data, such as Apex Legends stats or FIFA Ultimate Team content
any purchases you’ve made on the old EA Account we’re moving the games from, including in-game currency and anything you’ve bought using in-game currency
any EA games you’ve downloaded and purchased on Steam or Epic
any content, online and multiplayer data and purchases made in games accessed via an active EA Play subscription on the old EA Account
and potentially any offline saved data on your device.
I can only move full games (excluding FIFA, Apex Legends, SWTOR, Third-Party games, and games downloaded from the Play List from any active EA Play subscription on the old EA Account), so any Alphas, Betas, or Demos will be lost, and not moved to your new primary EA Account.

[If they have The Sims 3 content on their account: If you play The Sims 3 and have purchased Worlds for your game, the Worlds and any game saves you have with Worlds will be inaccessible. That means you will not be able to play any of your game saves and would need to create new ones without Worlds to play your game.]

Once we merge your accounts into the primary EA Account and all of your content is in one place, all of your old accounts will be deactivated.
