This happened to me just a few hours ago. I reported it and sent in the screen shot of the chat confirmation of what happened.
I was doing QL200 (normal) implants for someone. I saved the right HAND for last because the shining inner fire cluster needed 1k NP skill and I had to find an MP for the boost to get over 1k.
I put the faded and bright in with no problem. When I put the shining inner fire in, the implant changed to a QL200 jobe right WRIST implant (not a refined implant - a jobe implant) and all the clusters had been changed. I forget exactly what the clusters had become, but one had become a health or nano delta cluster.
Fortunately, I had a spare empty 200 rt hand in the bank that I gave the guy along with the wrist, but he was out the clusters he had bought (though he now has a wrist implant that may be worth something). I don't know if this is a consistent occurrence with 200 rt hands and shining inner fire clusters, or not. so just a word of warning.
