That is exactly the one I meant to refer to; the ideal scenario would be a modern speaker pronouncing Proto-Zapotec—I think that would be the closest possible approximation today.

It has to be Proto-Zapotec. One has to be careful because there are also intermediate languages between Proto-Zapotec and the Zapotec variants like Southern Zapotec, as is Proto-Southern-Zapotec for example. A fast search led me to a short Spanish Proto-Zapotec dictionary at the end of this 1973 publication: https://www.jstor.org/stable/1264826 (an account with Google can be made), but hopefully there are other dictionaries around.

Yes, I noticed because in these 10 minutes at last I kind of learned how to use the Editor In any case, my point in that link was not so much "two different mechanisms for the same effect", but that "there's no need for different buttons if the functions are similar and, if I'm not wrong, there's no overlap between them". Of course there are the differences you mention, but they are still similar things, although later on I stated that "maybe there's a case (or plan), to have structures that can be both garrisoned and posted (this should be the term, instead of "turreted")", in which case it would be fine to leave two buttons (although the "turret" naming should be corrected because, as I explained there, it makes no sense).

Sorry, they lose health, and fall off of it when they are killed.
