The errata doesn't contain any correction and efforts to search have not found any answers either, so:
The Japanese list in Colonies and Conquest states that Palisades are available Only from 1575, yet the Total Bases column states 0-12 before 1575, 0-24 from 1575
There is a thread for V1.09 Errata items in the general discussion, might be best to add that there, as well as in the rules questions section as there is a thread in there for each book for list errata.
