^ this. Bugs I've reported in recent times have been fixed with quite fast turn-around times, but if one doesn't report bugs then the devs will have no idea something needs fixing. Lich is great at crushing bugs very quickly and it's great having players listened to and problems solved quickly.
The only long outstanding bug that really annoys me is 'flashing textures' (z-fighting issues) that occur on the 64-bit client; I reported dozens about a year ago and they're still around. The floor between the quest givers and the AH in Wynwood Hall flashes, or the floor by Elminster in estar, or various windows/picture frames and behind the banker in Sharn, or a bunch of flashing textures in a various quests. Looked thru my old emails while typing this to check and I can see I bug reported these in May of last year, so 1 year later still around.
