Why aren't snippets included in help when building from command line.

Edition:

RoboHelp 2015 (with latest updates)

Operating System:

WIndows 8.1 Enterprise (64-bit)

Outputs:

Merged CHMs and merged Responsive WebHelp

The issue:

We have multiple projects that merge into a single help system. We use snippets extensively in throughout multiple topics.

Everthing works as expected when we build CHMs and WebHelp directly from the RoboHelp interface, which means the snippets are included in the output; however, when we build the same help (from the same projects) using the command line functionality, the snippets are not included.

Anyone have a clue about why that might be the case?

Thanks.
