Hi !
It seems that after SL's September 24th 2019 update, the VixenTex plugin contained in the Vixen cuffs (especially the arms ones) tends to crash with a stack-heap collision, which means memory full. Nothing changed in the script but what used to work before stopped working after this SL update. I know the VixenTex plugin has always been borderline full on memory so to mitigate that I optimized it a little more and released an update for it.
The crash occurred when you go to the VixenTex plugin then choose a Preset, and to fix it you'd have to hard-reset the cuffs. Annoying.
With this hotfix, hopefully you won't get a crash anymore. I have checked the EleganceTex, HighbindTex and StrapTex plugins as well, they don't seem to be subject to this crash, only VixenTex. You can get the hotfix by doing a simple update of your Vixen cuffs (and collar if you want) at any of my updaters, you don't need a replacement since the issue is located in the plugin, which is in the main items of the Vixen set.
You can find an updater at the following places in-world :
My little shop
Dark Wishes
Roper's Dark Playground
Chorazin's main store
It looks like an orb floating above a pedestal, just click on it and follow the instructions.
Please note that Pak (where my little shop is) seems very laggy these days and this interferes with the update process. I recommend you try one of the other three slurls in priority. Chorazin's place is the least laggy of all.
Have fun !

PS : Thank you TotallyIn Corrigible for the heads-up !
PPS : If this script crashes because its memory fills up more than it used to, I expect other scripts to crash in the near future, and needing an update too. I'll stay on the lookout.
