I have my whole party at the gate, yet when I click on it, they just walk in the spot, like they dont have enough space or I break formation.
I entered sewers before and I have unfinished business there.

Walk away, change formation, change leaders, come back, try again. Do whatever it takes, but eventually you'll get in.

I did all that.

Are you able to enter if you dump everyone but your main character?

How will that solve a issue? I don't want to play without party.

It might not, but it will tell you if party size is an issue. Save the game, dump your crew and try to go in alone. If that works, after saving the game quit to the desktop, restart and reload then try again. Going through certain doors has always been fraught with issues in this game.

Failing that, do what you should have done from the start, state exactly which game (and which edition) you are playing, what mods you have, if any, precisely which sewer entrance you are trying to go through and there may be a workaround via the console.

Maybe try an other enterence? There are multiple entries to sewers.

I already tried that. I try as you suggested. No dice.

Im trying to enter temple sewers, have lasted update, have no mods and I tried every entrance.

Please, help me.

Its BG2EE.

All three of them. And all three of them are not working.
In the ch2 theres temple district with three sewer entrances.

If you've been there before and now you cannot, I'm going to suggest that your save is corrupt. Here's something you can try to see if area transitions are indeed bugged. Open the console and type:

C:MoveToArea("AR0701")

Type it exactly. That should take your party into the sewers. Now, try to get back out. I strongly suspect that you will not be able to, in which case you need to go back to a previous save that wasn't bugged.

I do that, but area is totally empty! I defeted the fee-demanding foes, but I didn't defeat Rakassha and kobolds group and they are gone!


And there's no sounds, locked illithids dungeon is completely open.

is there any alternative....

From the details in your previous post, none. Your game is corrupt.
