No, at least for PC users.
This one and several others will be fixed as soon as the SDK will be released. It is a very simple issue, it is surprising it was not fixed in the patch already.
Well, yes, for those of us on PC most of the glitches and graphics issues will eventually be fixed.
Anyone seen nirnroot repsawn? While I cant be 100% certain, I am pretty bloody sure they are respawning in some locations for me. There is one in Darkstar Im sure ive picked up at least twice.
They respawn just like any other plant. That's when you'll see the cumulative leftover lighting effects — the more you pick the same Nirnroot, the brighter and uglier the leftover lighting effects become. They "stack" on top of one another.
