Stuck in dionysus park with 4th little sister

[MegaDarkKebab]

So I'm playing bioshock 2 a little lately, doing like 1 or 2 lvls a time. But now I'm in Dionysus park lvl and I'm just about ready to leave but I have a little problem (pun intended).
While I had the 3rd little sister ride my shoulder I ran into a 4th one and ofcourse quickly murdered her big daddy and as soon as I had gotten rid of the one I was occupied with I went back to go get her.
And here is where my problem began, I picked up the little sister and then the big sister came to beat some sense into me (failed ofcourse =P).
After this I noticed there are no more adam corpses around so I proceeded to leave the area by train. But now when I approach the train I get a popup message saying I can't leave while having a little sister on me and I have to drop her off in a vent. Now when I go to a vent I litteraly cant do anything, no harvest, no rescue.
I'm hoping anyone knows a fix for this, I googled a bit but I can't find anything on it.

There simply shouldn't be 4 little Sisters.
Pause the game and check to see how many Little Sister icons there are - as far as I remember there are only 3.

Yeah, there are suposed to be 3 but I came by a 4th one having the third on my shoulder, I don't know why or how but ofcourse I wanted to take advantage of it but that seems to have backfired.

Googled again yesterday and people on the xbox have had it too but they said if the 4th was picked up after messing up the big sis she could be used. But as my game is messed up now I most likely have to reload prev save meaning redo the lvl. I was hoping people on here knew a solution but it seems like I had a little bit of bad luck.

Guess I won't hang around waiting for a solution as it doesn't seem people know much about this but it would still be nice of people were able to post a solution incase anyone els gets caught up in this mess.

That is a weird thing to happen though. A pretty huge bug in the game.

The only thing I can think of besides loading an old game is somehow hacking the new savegame so you don't have a Little Sister with you anymore. How that would look like exactly - I don't know.

Sorry that I can't be of any help.

Worst part of that bug is that the xbox related posts about it are about 4 to 5 years old.....

Well, fair enough, bioshock 1 has 3 extra little sisters one can get by avoiding a scripted event untill all the little sisters are dealt with. Because that scripted event is basicly big daddy fighting off some splicers protecting his little one and if done correctly you can trigger that after getting "all" little sisters. Now bioshock 1 is a bit older than 2 obviously and they still haven't even fixed that, doubt they will either.

I guess tomorrow I'll just continue from older save because I absolutely have no programming skills to hack that save or figure out some sort of console command to clear it all up. Hope people will find an answer and will bother to share with everyone though.
