Cool.
The only way I found to add the propelled part of the Evington was to add it as an Underbarrel weapon; it's not perfect, but at least it works.
Sending you the file as soon as I've verified that it all works. I'll post the XML code I've used here as well for reference.
[EDIT]
All right, all done. There are some caveats to these mods, just so you know.
TPP; no issues.
Ultimax 70: no issues
AN-39: Weapon commlink has no stats, flare comp and low light for Imaging Scope added as camera upgrades. Also note that smartgun system has also been added to grenade launcher
Terracotta Arms DLW: Low light for Imaging Scope added as camera upgrade, environment modification is not specified as Arctic
M428 Grenade Launcher: commlink has no stats (no upgrades exist in chummer for this; you'll have to manually add a custom commlink with the stats as needed)
Kriss X: No option to add flashlight and laser sight as options; each can simply be unchecked as "installed", however
XM-629 OICW: This one also does not have stats for the commlink, and I'm not sure whether the AR and GL are both supposed to have 2 RC. AR has been configured to use SMG ranges, however, and shock pad adds to inherent RC of 2 for a total of 3. Let me know if this is incorrect.
Evington Propelled Katana: No issues, except propelled stats had to be added as underbarrel weapon. Range is set for tasers, though skill used is still blades. Let me know if this is incorrect.
General:
Concealability rating for some of these may or may not be accurate; underbarrel weapons add +4 to ARs existing 6, for example.
Here is the raw data that I've added to the weapons.xml file in the chummer "data" directory; let me know if you want me to send you a copy of the updated xml file, or if you're good copy-pasting this into your own XML file.
