Nightfall Event Left Behind a Few Bugs?

It seems that, although ArenaNet claims that the update "reverted" GW to its state before the Nightfall content was uploaded, it seems that some new bugs have arisen in the process.

1) Connectivity errors. Usually I can log in instantly, or pick a character instantly. Ever since the Nightfall Event started, I have had the "Connecting..." window appear for up to 10 seconds when doing either of said things above. My internet's speed hasn't changed a bit, so surely it has to do with GW. I've also seen more Err7 complaints arise here at GWGuru.

2) Particle effects missing. Many people, as well as myself, have noticed that some spells now sometimes do not show their particle effects upon being cast. Prime examples of these include all running skills, in which there is a chance no spell artwork will appear.

3) Loading icons. If I remember right, icons loaded instantly (or at least almost instantly) before Nightfall, and there was no need for the hourglass icon. Now it can take a fair amount of time to load the icons, and the hourglass icon is really distracting.

I''m pretty sure that ANET knows already.

And the loading icons bug was reportedly discovered BEFORE the NPE started.

phew and I thought I was the only one
