Welcome to the Q&A Forum

Hey Vaz, I didn't see any news about a big update of the Google algorithm recently. The reconsideration request take some time to process, if the hidden links were the cause of your lost rankings, it should come back soon now that you fixed the problem. Check your (old & new) competitors backlinks via Open Site Explorer or Majestic SEO to see what they did to be ahead of you in the rankings. If some of your competitors lost rankings too, maybe they were hit with the same problem as you (malicious code/hidden spammy links). In any case good luck with your website !
