Patch 5.0.3 should be up shortly (ETA 1 hour). Sorry about the Mawrth crash, nothing we could have avoided: it was an obscure engine error.
Took 2 1/2 hours and 20 builds to find the ONE rock on Mawrth that had a shader error.
We will be doing some testing ourselves, but have limited time/resources. Please let us know if there are anymore issues so we can fix them!
