OK. Can you provide a .pto from a very early stage, i.e. prior to doing
any refinement, say just after generating control points for all images
and no optimisation steps performed?

Here it is.  I presume that control point generation is deterministic.

Using this .pto (almanor-16-bad-1.pto), if I deselect images 1,3,5,7,9,11,12 I can then optimise everything without all hell breaking loose. I optimised in steps, positions, positions and view, positions and barrel, positions view and barrel, then everything. Are you able to reproduce this behaviour? Whilst this might not be an acceptable workaround for you, the mean error is 3.1 pix, max 12.4, it is still considered a good fit. It doesn't solve the basic problem, but maybe adds a bit more info to help track down the cause.

Cheers,
