Update 8:56 PM PDT – EU shards are back on online with the update that should fix the crashes.
The EU shards were updated with RIFT 2.7 Hotfix #5 and Hotfix #6 today. Some of you may be seeing the game crash every now and then.
A fix has been found for the crash, but CM Morgana has mentioned it will take several hours to be added to Live:
The issue causing the shards to crash has been fixed by our development team, however, the time it takes for the fix to be added to the build, QA time, and more means that it will be several hours until the update is ready. I’ll post any updates in this thread as they come in.
Sorry that this is happening to you guys, and we appreciate your patience as we get it taken care of.

So for now if you are in EU and your client is crashing – Trion is aware of the issue.
You can follow the thread on the Rift forums here to keep up to date with the situation as it gets fixed.

Sadly, this patch/hot fix forgot to fix one important item issue which is the mage tanking essence (Screaming Bloodfire).
ye I have had crashes lately… I thought it was my drivers but i guess it wasnt. Hope they fix it
