Well,
this one's a doozy…

For multiple characters so far, I've seen the game start breaking and behaving weirdly shortly after I found EoR's Medical Urgency Vest, and by pure serendipity, I managed to track it down to this addon. I guess no one else is using it?
So here's the scoop: Medical Urgency Vest confers a talent named (appropriately enough) Medical Urgency Vest when worn, which handles the pseudo medical injector provided by the armor. Naturally, we try to describe that conferred talent in the object's tooltip (that's our job, after all) — but this talent's .info() method
really isn't expecting to be called before you've worn the armor and it's done its setup stuff. It doesn't completely blow up everything, since we wrapped it in a pcall(), but it does enough damage that the talent is left stuck on the player in a partly inconsistent state, whence it can randomly pop up and break stuff (notably, occasionally causing
"stuck" temporary effects).
Anyway, practical upshot, v1b fixes this by temporarily installing the necessary inscriptions_data{} from the object just long enough for the talent description to have access to it. This also affects Life Support, I think, since it has a similar talent, but I've never created it, so I can't attest to it.
