I recently submitted a manuscript to a well-known journal in my field. It is published by Wiley and Hindawi. I received a "major revision" decision based on two reviews. One of the reviewers uploaded the annotated manuscript (he made comments via the Word comment function) to give his comments. As such, I was able to see his name. I do not know this person but based on his scientific output he is big in a particular related sub-field. All comments were valid and easy to address. As such, I resubmitted a major revision within 3 days (working full-time). Then suddenly I received the message below. Based on the submission system, they are now looking for new reviewers.
Could you help me decipher the meaning of the message? Is it because I know about his identity (the review is supposed to be single-blind)? Is it because I was so fast and now they suppose something "must be wrong"? Any comments will be highly appreciated!!
