There have definitely been problems with 17.1.1 (for me, it caused me not to be able to use the BranchTrack and eLearning Brothers tools, for example). I know there’s a patch/update coming out for 17.1.1 within the next week or so to fix that, but I don’t know what other things might be getting bundled into that update, if any. I’ve had some pretty weird, random things happen with variables lately, too, but I don’t know whether that’s because of the update or “user error” yet. However, from looking through the posts here, it does seem like 17.1.1 has issues (and maybe should have been tested a little more thoroughly before its release?). On the plus side, I do think Trivantis is working to fix some stuff ASAP!
