First of all, thanks to the team for the great work on Spine!
A couple members of our team tried to use the Photoshop export script, and for both of them, it causes Photoshop to crash when exporting seemingly ANY file. In addition to our own assets, we tried with an empty PSD, and a PSD with a single filled in square.
We first used the script earlier this year, and had no problems, but it now crashes on 2 of our machines, even when using the same PSD's which had previously been exported successfully. Both machines are on Windows 10; one running Photoshop CC 2014 and the other running the latest version (2017.1.1).
I took a look at the script to try to see if I could narrow down the issue, and it appears to be in the "hasFilePath" function. When replacing the code with "return true", the script runs as expected (provided the document has been saved, of course).
I'm happy to have a workaround, and hopefully this can help others who might be having this issue.
I'm not familiar with Photoshop scripting, so I can't begin to imagine what the issue is, but hopefully I've helped get you guys closer to finding a proper fix. If there's anything I can do to help further, please let me know.
Thanks again!
Jordan
