I've had no additional errors since the update, however, I don't know if this is new or I hadn't noticed it .. but it is no longer showing the event in the tracker UI.
So .. it used to give the number of the tracked raid in square brackets, the date and time, and then the name of the raid, if it picked it up - and it usually picked that up if I was in a proper guild raid group. But now it is no longer showing the name of the raid.
I also noticed today that, although it is importing this information correctly into the website, it is not giving the correct ilevels of gear in-game. So the addon interface is showing the loot dropped tonight, for example, from heroic Eternal Palace, which is generally 430+ gear .. and did indeed drop 430+ gear.... however, mousing over the gear shown in the addon shows the baseline 400 gear. Even the stuff that was warforged .. it doesn't show that on the addon.
For example Luminous Jellyweed looted by Vampirsha here: http://www.darkwolves.eu/rapid_raid/raid_details.php?raidId=1578363&raid_pool=189145&gid=180473 was 435 ilevel .. and shows as such once imported .. however, in-game, in the addon, it says 400.
