Updated to 1.5, no edits whatsoever except to the about.xml

Updated to 1.4.

Just a matter of adding "1.4" to the about.xml. I have no red errors popping up and leathers' values seem to be properly updated to the tweaked values.

Hotfix for released update;
-Quick fix for released update, pressed "update" a tad too soon. All is in order now.

Update 2:
-Removed hard requirement in about.xml so that it can be used with Cosmic Horrors - Xml edition. Users can now use this patch with either base cosmic horror mod, or the xml edition. Make sure you have one of them in your load order!
-reworked the tech level patching to work with the new factiondef of Cosmic Horrors - Xml edition.

update 1
-Tweaked leather stat values a bit more
-nerfed marketvalues of leathers in general, even though some have been buffed to be on par with others.
-Added in a patch to make the hidden factions industrial tech-level. Needs testing, but should work without issues.
