Recently several people have reported Second Life clothing display problems when using a text client to login their avatar. Users of both METAbolt and Radegast have seen problems which do not appear when a standard viewer is used (e.g. Viewer 2, Phoenix). I've verified this myself using a jacket layer corset from a Pandorabot owner.
You can read the METAbolt Forum topic discussions here and here.
The problem appears to be in the interaction between the libopenmetaverse library and the SL server code. Further complicating matters is the fact most clothing layers display properly and only a few items have been seen to display incorrectly.
So, what does this mean to you, the Second Life Pandorabot owner ? Well, if you do not use a text client then you have nothing to worry about. If, however, you own an Actorbot or METAbolt Add-On and log an alt in with one of these clients then you may see problems. Currently there is no known workaround and any fix needs to come from either Linden Lab or the Open Metaverse Foundation. All you can do is, after logging your alt in with a text client, login with a standard viewer and check your alt's appearance. If a clothing layer is not displaying properly you will need to replace that clothing item with another.
If you see any display problems with text clients please let me know and I will pass the information along to the appropriate forums. Hopefully this will be fixed soon.
