Ran the 1.4.2.01 update-to-latest-db.mysqldiff.sql on Database Version: 18.104.22.168. Got one error for the first pass, and the other with all the additional passes.
First time thru...ERROR 1062 (23000): Duplicate entry '6083-AMOEBIC-en' for key 1.
Second time and forever...ERROR 1061 (42000): Duplicate key name 'concept_word_concept_idx'. Darius thought you might like to spend the holiday weekend with our concept dictionary and this error message. I did run these commands by hand:
For dessert, I ran "Update concept word" (using a large range of 0-10000)
The database seems repaired and fine.
