DC Protection in Deep Dungeons not working as intended (Party)

[Stotefarus]

Before the 7.4 patch release, when someone eventually DC'd, the nickname would go gray and the player would still be in party with us, then after they join the game again, they loggin -> INSIDE <- the deep dungeon with us to continue our run.

Now, after the patch 7.4, whoever gets disconnected, get removed not only from our party but also from the deep dungeon run itself, they loggin inside the "waiting room"(the one which we can choose to go to the next set or back to "Eorzea").
The disconnected player is still in party with us, but to us hes long gone and theres no way to communicate with them and/or bring them back to the run.

Whenever we finish killing the boss, a message will pop up asking if we wanna finish the run w/o the DC'd player and we forcibly have to say yes, which leads to a dead end/run.

What that means?
In our savefile it will show a "pokeball" next to the disconnected player (character not found -- even tho hes right there with us) while to him it will show that everything is normal as intended, but still we cant continue that savefile because is "corrupted" now.
Even tho it says Party KO:0, it gives us the error message saying no one is able to continue the run.

This is ruining our experience in game alongside with the DDoS attacks, so please, look further in this bug because I believe this is not what you guys tried to introduce in this new DC protection system.

Thanks.

EDIT:
I also learned if you DC in floors 31-40 in HoH, you go back to eorzea straight away instead of the waiting room. You can see in the Part 1 of the video in the character's main menu I was on Heaven-on-high and ended up in The Ruby Sea.
This also might happens aswell in the Palace of the dead floor 51-60, Eureka Orthos 31-40 and any floor after any checkpoint in Pilgrim's Traverse.

They asked me to record in game so here it goes. Its unedited btw.

To add to this, the change to protect from DDoS attacks in deep dungeons is also not going to be effective in a lot of cases:

1. If 2,000 players disconnect on a given world, then the queue to get back in is extremely long and takes more than 10 minutes.

2. If a player is fighting an enemy when they lag or disconnect, the enemy will likely kill them. A way to solve this could be for the server to detect abnormal ping or packet response times, and apply a temporary invincibility buff.

3. A patrolling enemy may attack a player and kill them.

PLEASE take a look at this SE! This has ruined multiple runs that I've had in the last week! And what's worse, the game actually gives me a 30 minute penalty for being kicked out! I don't have a huge amount of play time each day, and this is leading to so much lost play time it is insane.
