Hello, I was unable to find what happened to your Patch EF, nor how you even received one in the first place. However, I was able to determine that you did sell a S EF to the shop for 7.5 mil gigas. When you get 7.5 mil gigas again, and want the EF back, send me a PM linking me to this topic, so I will remember what it's about.
Thanks,
~RedEyes.
