Concatenation seems to be using a cache

[stones]

When I pipe my filtered javascript files into concat, it seems to use a cached version because none of my changes are there.

If I don't concatenate them, the individual files are correct.

Any ideas?

edit: Sorry, that wasn't very instructive. I forgot to mention I have:

• deleted my destination files to make sure that the file is a fresh version
• I have drastically changed the files ( removing 90% of the content )
• I have deleted my npm folder
• updated to the current version
• Made a new gulp task which pipe all filtered JS into a new folder, and another function to read that folder for all js to concatenate
• Output concatenated file to separate folder.

SORRY!

It was working as expect. I had 2 data sets that are very similar being concatenated and I was checking the wrong one.
