OS and version
Mac OS X 10.11.6
When you print a script that contains a very long, multiline calculation expression or comment, FMP does not print a number of the script steps located after it.
The bug behaves that way on Mac OS only. It is also buggy on Windows, but a bit differently: it does not print the last part of a long, multiline block of text.
How to replicate
Try to print the test script in the file I've attached.
Do not create any long, multiline stuff?..
