I'm at the part where I just went in horsepath track, took the discus, went back in dread house ,talk to David who agrees to do the horsepath discus experiment and called Helena to confirm same time of experiment. Now I'm supposed to jump to St.Edmund Hall ans the lambs but they're not there. Did I forget something? Thanks for your help. Sali

It's difficult to know what was missed in the game but check:
The progress of the score or gameplay can be seen by using the P key or clicking on the Progress icon (with 3 lines on it) on the cards-mask icon at top left of the screen (left of inventory).

At this time, all the other subchapters in this part should be 100% for you to move on. See which one you have not finished.

Also check the map -
Gold location still has a puzzle or bonus action to be done.
Silver location still has bonus action to be done.
Gray locations are finished locations.

Keep us posted.

MaG, I see that "altering plan"is at 92%. On your wk you say:"get Eddie's phone". Do I have to do something to have it? Also, after I told Mephisto that David refused to change the time of experiment I went out the store before I called Helena to confirm the same time for experiment. Could that be the problem? It's then that I jumped to St.Edmund Hall and didn't see the Lambs.I hope what I'm telling you is clear anough.

sali,

Eddie will give you his cell phone number - not he phone itself. So talk to him a lot.

I don't think the going out to the street will affect the game. Talk to Mephisto completely also.

Keep us posted.

Mag, I replayed the game and it goes well. Didn't find what I forgot the first time. Thanks for trying helping me. Sali
