As of the last two times I've logged into SK since the new updates, I've been having considerable trouble in the Clockworks, on Missions, and in Haven as well.
I'm pretty sure this is not just a simple lag issue, since my laptop had only just booted up the last time this happened and since this hasn't happened before.

It doesn't occur all the time, but at various intervals during my Prestige Mission run, I was rendered unable to attack or move. When I attempted to attack, it resulted in the beginning of the charge animation being shown, without being able to cancel it; when I attempted to move, I was continually rubberbanded back into the original position. Shielding was also glitching; the start of the shield animation showed (lifting up the shield), but the effect itself did not appear, which also prevented 'shield-bumping' and resulted in painful death. (Yesterday this resulted in death by shadowfire; today I was stuck in place whilst attempting to flee from grimalkins.) The lack of ability to attack also carried over into inability to pick up objects.
(Damage taken also took some time to show up on my health bar, and the ce revive option completely failed to turn up whatsoever, although admittedly this has previously occurred with 'ordinary lag'.)

This is completely different from what I would call 'ordinary lag', when moving objects continue to move offscreen in the direction they were originally travelling in. I have had this before; the attack animations still show up normally when I am under the effects of normal lag, and don't glitch (although whether or not anything gets hit is a completely different issue). Any damage taken doesn't show up either.

Has anyone else been experiencing problems like this? I haven't found any recent posts mentioning similar issues on the forums, although it might just be that I'm blind...

Edit: F2 bug report submitted as well.
