Error: vector_sub_Ab: wrong dimensions (v2.1.4)

This is a new one to me. Seems like it happened on the " (3 px, 2 3d) sigma filtering" step?

Aligning 37841 images from a multi-camera downward-looking rig with 4 cameras in a triangle config. Separate camera configuration and lever arm offsets with precise positions. Last bit of processing log:

Hello Andy,

Is 37841 - a total number of images in the project or it is a number of multicamera systems (so over 150 thousands of images)?

And if you can try 2.2.3 version for the same project?

In case the tie points are stored in the project after this failure, maybe you can also share that project, so that we could try to run alignment stage based on existing tie points and see, if we can also get to the same problem.
