jsidhu762: Select the group and press the stop button. Then select a party member and tell him or her to move somewhere. Keep doing that until there is some distance between all of them. Now select them all and click on where you want to go.

Edit: when you are spacing your party out, click on the portrait on the side instead of clicking on the model on the screen.

jsidhu762: I believe something was lost in translation, and I apologize for that. Select your group, and then press stop. We are going to forget about where your destination is for the moment. Click on the portrait of one of your party members. Now click on a spot that is a few meters away from everyone else. Rinse and repeat until you get something that looks like this: https://imgur.com/a/Rmayvm2

Now select all of your party members, and click on where you want to go.

L0ngT1meGamer: Here you can see an overview, with some dialog too. they just won't budge. Sorry for my noobiness!

amazingchestahead: This is a bug with the EE, happens if you start the tutorial with a custom party with several companions. This tutorial section was originally from BG2 and was reproduced in BGEE. Vanilla BG doesn't have this section, and in vanilla BG2 you can't create a custom party for the tutorial. I guess they didn't play test this section with a custom party, if they did play test it at all.

If you just use the console (CTRL + Space) you can teleport the companions to another area then teleport them back, that would unstuck them.

Hickory: Enable cheats in your game. CLOSE THE GAME FIRST:
In baldur.lua insert under 'Program Options'
SetPrivateProfileString('Program Options','Debug Mode','1')

In-game press CTRL+SPACE
Type:
C:EnableCheatKeys()

Select any or all of your party. Hold your mouse where you want to move them. Press CTRL+J.

jsidhu762: This happened to me innumerable times and I didn't use a custom party.
