The bulk update request #2117 is pending approval.
mass update pinkamena_diane_pie -> pinkamena_(mlp)
Reason: So apparently Pinkamena Diane Pie is the full name of pinkie_pie_(mlp), but all tagged images use it for pinkamena_(mlp) instead : pinkamena_diane_pie.
This looks like an "Update and Forget™" moment:
An alias to either pinkie_pie or pinkamena would be easily confused (bronies will use it for pinkie_pie, others will continue mistaking it for pinkamena).
