The problem will be fixed in the next update.

Here is some background information: I am using a zip library which is using the "fopen" function to open files and "fread" to read their contents when creating the zip file. Unfortunately, the code never called "fclose". So while creating the zip file, the app would run out of file handles and silently fail to add all files to the zip file. I added a call to "fclose" after each file was written to the zip file and now it works correctly.
