Don't really know where to start but I'll give it a go.
Character Creation
Lore (World), Lore (Animal), Lore (Plant) still appear as common skills.
Only eight of the professions seem to have been updated (and six of these still with RQ1 common skills (see above)). If I want to create and Acrobat (just taking the very first profession on the list in LU as an example) I'll still get the RQ1 common skill Throwing which no longer exists in RQ2. Haven't looked at the others that aren't in the errata but I suspect this isn't an isolated example.
Sorcery
No errata at all - though if you create a Sorcerer from this errata you do get the RQ2 skill Manipulation - the Sorcerers in the NPC Stats still have the multiple Manipulation Skills - with there being no errata on Sorcery there is still no mention of what constitutes a RQ2 Grimore (a single spell ?) in LU.
NPC Stats
Fafhrd and The Grey Mouser - RQ1 Lores listed as Common Skills, Dance as an Advanced Skill - no Sorcery for The Grey Mouser (though this may have been a design choice - still a bit odd though)
Basic Typos
Swimming instead of Swim, Tracking instead of Track (again RQ1 instead of RQ2) Thief Second Class has a rather amazing Resilience of 4333%
