The commlink thing's fixed in 5.178; as a workaround, if you make sure your RCCs, Cyberdecks and Commlinks are at the TOP of the list, it won't crash. Currently it tries to loop through all of your gear to find a specific commlink, but then it tries to convert the gear into a commlink to check what it is. Anyway, fixed in 5.178, which I'm hoping to get out tonight.
As for the life modules, I've been meaning to go through the life modules and vet them all properly. Currently it's still in pseudo-beta, so it's not my highest priority. There's currently no reliable way to select from multiple choices for life modules; I suspect I'm going to have to build up a new form like the mentor spirit selector to actually handle it properly.
Neijia and Strike the Darkness are in sidebars on page 140 and 141 of Run and Gun. Neijia's for beating up spirits, strike the darkness is for being Zatoichi.
Descriptors for gear is a bit of a thorny issue. Unlike Herolab and their ability to bribeconvince CGL to look the other way, Chummer is restricted by an inability to reproduce text in a copyrighted document. Something something not transformative enough, something something I can't be bothered dealing with legal headaches for a programming challenge. I'd want something from CGL clarifying the limits of what can be done before I put any serious work into implementing that.
