Howdy Deku!
Scrota still exists and will for as long as they leave the Ethernet/immune shield patch stuff in effect. We saw some of the same lag based issues related to him not kneeling when he should, etc. It seems improved overall so far, no quick stand or disappearing sword BS from the very small sample size of 3 kills we did this morning. The wording of the patch notes makes me a little nervous though, didn't sound like they truly fixed everything (as also evidenced by some of the usual BS we saw today).
Quick-stand sword swipes were only one version of the glitch, sometimes he would stand normally but still smack an invis Hunter. Too early to tell if both versions are fixed. Also, swords often didn't disappear "immediately" or w/e the patch notes said; it was usually after 3-5+ seconds on the ground but hopefully that's just a semantics technicallity. The last part about the 30 second sword timer was a total non-issue since the sword should never have sat around for more than 15 seconds. Nothing has changed now, it's the same 30 second time with the same 30 second music clip.
Of course boring encounter is still boring, no bug fixes can save a fatally flawed design.
