Droplet misses opening/processing files in a batch, but does process them if dropped again
Help - I thought I was loosing my mind, but I've tested carefully and this is definitely happening.
Background: I have a droplet that does a number of manipulations to images that I send into photoshop as .NEF files. The action outputs .PSD and .JPG files. I have sent small batches of files into this droplet to produce a total of 31 .psd/.jpg file pairs. I created another droplet to do another simple manipulation to output a temporary file with a transformation I need for printing.
Problem: When I select all 31 .jpg files in finder and drop them on my droplet, Photoshop does not output all 31 files. Some number, but always the same files, are never opened, processed, and output. I tried to analyze a small section of the batch by selecting the first 6 .jpg files (1.jpg through 6.jpg) and dropping just those onto the droplet. I noticed that file #1 and #3 in the sequence are definitely never being opened by photoshop. The history logging to text file feature explicitly shows these are not being opened & closed. Even if I rename them so that they are ordered differently in the set, these two files do not get opened and processed when I select the batch of 6. However, if I select those files (1 & 3) either individually or as a pair and drop them on the droplet, it outpus the proper corresponding 1 or 2 output files!
Question: What on Earth could this be? How can I debug? And is there a way to get this to be robust? Once my batch sizes get bigger, this is going to be a real problem. THANKS for any help!!
I'm on a M1max Mac Photoshop v23.5.1 Apple silicon version
Just in case you're still reading: Below is a copy of the log where I've reverse renamed the files 1.jpg->66.jpg, 2.jpg->55.jpg, etc. Again, files 1(66) and 3(44) never got opened. Then I selected only 44 and 66 and dropped them on the droplet again.
