UserDirected Enabled Interactions - Enables many of disabled interactions that have never been seen by the player!

(UPDATE 1): Added a separate mod which only enables "Swim Around - Sim" and "Swim Around in Ocean - Sim" interactions, it only requires Base Game. Thanks to CMaxi for letting me know!
-------------------------------------------------------------------------------------------------------------
This mod enables several interactions that were disabled by EAxis, or some debug interactions that EAxis were developing and were never seen/have been completely deprecated by the player.

Why are many interactions disabled?
During development, the team behind The Sims 3, its EPs and its Store Content had to check that some interactions work correctly. After checking the turnings (so that players wouldn't see how some interactions were), they disabled them by setting "DisallowUserDirected=True" and "DisallowPlayerSim=True", this mod sets the values ​​"True" to "False", so the players can see what interactions are disabled by EAxis developed like you've never seen before.

How many interactions were disabled?
There are a total of 138 interactions disabled in the Base Game, EPs, and Store Content. Here are the interactions that have been disabled in alphabetical order.

EPs & SPs Required:
You need all the EPs and all Store Content for the mod to work. SPs are not required because there's not an interaction I could find to make it available. Of course, if you don't have Into the Future, for example, the mod will ignore every EP11 values so the mod will still not cause any problems to the game, it'll just simply ignore.

Issues:
No issues were found with the mod! However, if you have any issues with the mod, please reply in the comments section, so I can try to solve your issue.

Uninstallation:
Uninstalling is perhaps not a problem. Make sure that your Sims is not using the interactions I've provided in "How many interactions were disabled?" section by cancelling their interactions so there wouldn't be any issues. Just delete the mod in Packages folder and you're all set!

Conflicts:
This mod modifies 138 ITUN interactions in GameplayData.package, so if some mods are using the same ITUN, it'll conflict.

You can check for conflicts in TS3 Dashboard and delete the ITUN you've installed, or you'll get a conflict between my mod and the other ITUN mod you've installed.
