2 image disappeared after aligning

[Fotografia]

Hello everyone,

 i'm trying to align a panorama with 2 rows and 2 columns, so 4 images.

I have added all the points manually (often with repeated details i have problem with auto align, this time i haven't tried and i just added the points manually), then i pressed align, the alignment was good, then i've choosed rectilinear projection and both in the preview and in the result i've lost 2 images and i'm unable to recover the full view.

I post a link to the project, the images where tif files with extension .tif, since they are really heavy i have converted them to jpeg with extension .jpg (i hope it could be possible to simply change .tif with .jpg inside the pto with a text editor).

Thank you in advance.

By the way, if i have for example image 0 (lower left), 1 (lower right), 2 (upper right), 3 (upper left), is it enought to add control points between 0-1,1-2,2-3 or also between overlapping parts of e.g. 0-2, 0-3 and so on?

I managed to make it work by optimizing manually:

1 - select all images in first tab and reset everything.

2 - optimize for positions (incremental...), note the standard deviation value (4.59 on my test) and press Yes
3 - optimize for positions and view, check that the new standard deviation (3.08) is smaller than the previous (4.59) and if so press Yes
4 - optimize for positions and barrel, check that the new standard deviation (3.26) is smaller than the previous (3.08) and press No (I could have avoided this line, but this is to explain the procedure)
5 - optimize for positions, view and barrel, check that the new standard deviation (3.18) is smaller than the previous (3.08) and press No (I could have avoided this line, but this is to explain the procedure)

6 - optimize for everything without translation, check that the new standard deviation (0.47) is smaller than the previous (3.08) and press Yes

The result now seems correct.

I am using 2016.2.0.be8da0221960, but my procedure should work with your version of Hugin too.

Of course, this does not explain why the procedure you used did not work.

Thank you this step restored all the images!

Thank you for the explanation!
