Well, it's even more interesting because LootSlot is not actually a protected function. ;)
Blizzard's way of determining where taint comes from, or even what is tainted, is pretty worthless. If nothing is actually happening that interferes with your gameplay, or that you can even tell is happening (or not happening, as the case may be) I'd really just ignore the warning. If you notice the warning being triggered consistently when you perform a certain action, try to figure out which addon is involved in that action. Then, disable that addon and perform the action, and see if the warning is triggered. If it isn't, then you were right about the cause, and should report the problem to that addon's author.
Shadoweric, Acheron does not ever call the function LootSlot; you can verify this yourself by searching its files. This is yet another downside of embedded libraries... all taint issues caused by all addons using libraries are attributed to whichever addon's copy of the library loaded first. In this case, Acheron loads first since it comes early in the alphabet, and some other addon using one of the libraries it embeds (most likely AceAddon-3.0) is trying to call LootSlot. If you disabled Acheron, you'd still get the same "error" message, with another addon blamed. If you have something that lets you search the contents of files on your hard disk, search for "LootSlot". If you don't, look through your addon list and take a guess at which one(s) might be trying to do stuff with looting; chances are one of them is the problem.
I'm seeing the Unknown issue in the raid I'm in right now. When I look at the death report and look at the tooltip for an individual line item from each one, it's all for the same guy and that guy happens to have a weird character in his name. (It's also a guy who hasn't been in our raid in a while so that could be why I wasn't seeing it before). Maybe I'm reaching, but can anyone else who's experiencing the issue corroborate a pattern there?
Nope, the guy whose report screenshots I posted was "Picturesque". Nothing weird in his name.
I've been seeing some odd issues lately with the health display in Acheron... guessing it may be related to the "Unknown" issue. Clear All doesn't necessarily fix the issue... it seems totally random. I'll log in and it will be fine. At some point, I'll look at someone and it'll be messed up. Whether or not I clear it, if I look some time later, it might be working properly again. Here are screenshots of both relative and absolute health:
Yes, the "do you want to clear?" spam has led me to simply disable auto-clearing. It does it even when nobody has joined or left the raid group, though I haven't done any formal testing to try to figure out what conditions will trigger it.
It is a bit unintuitive though. A tooltip on something (the output dropdown, maybe?) that explained this might help. Also, I'd suggest either resetting the output to "none" after reporting, or moving the report function from "left-click" to an entry in a right-click menu, or a modified click of some sort, to prevent accidental reports. Or move it to a separate button labeled "Report from selected entry". :)
With regard to purging data, I'd say just keep it until the user either logs out (at which time it's all deleted) or joins a new group (at which time the user is promted to delete) or uses a manual command to delete. Playing two feet away from someone who just wants addons to work as expected, and doesn't really care why when they don't, has given me a whole new perspective on addon development. Require too much user input and it's "why can't this just do ____ on its own?". Do too much without asking for user confirmation and it's "#$%#@ing addon just deleted all my stuff!". :p
I'm not currently raiding, but since I'm in charge of keeping my boyfriend's addons updated, I'm trying to get him to use as many of the same addons as me (i.e. Acheron instead of Grim Reaper). However, he's experiencing some issues with 1.0.4 (latest version on WoWInterface as of right now):
1. After a wipe, only 13 of 25 raid members were listed in Acheron. He hadn't released, so all of their deaths should have shown up in his combat log. I know there were some issues with this a while back, but since I haven't been raiding at all, I don't know if they were ever resolved, or if there's any kind of workaround.
2. After the raid, he wanted to go back and review deaths, but people who'd left the raid group were no longer listed in Acheron. (He was still in the raid group.) I think this is probably intentional, but would it be possible to not immediately purge people who leave the raid group?
To build on my last response to this, it seems there is a DataBroker display addon to show plugins as minimap buttons. It's called Barrel; youu can get it on files.wowace.com, or read more about it in the following thread: http://www.wowace.com/forums/index.php?topic=14487.0
