For display issues, such as a mob/NPC appearing with an incorrect name or your map not loading correctly, you may want to try using the /reloadui command. If that does not correct the issue, please recover your client using the following steps:

Launch the Glyph patcher
Sign in to your account
Right-click on RIFT in the top-left corner of the launcher and select the "Repair" option.
When prompted to begin file recovery, please click the "Yes" button
Allow the repair process to go through
Re-launch your game
