Alas it was not some megaproject or megabeast that brought about the doom of Spearwaved, but rather user-error. I think I may just have to set up a backup script of some sort to prevent a miss-click from ruining too much of my work in the future. The good news? I was able to run the fort long enough to discover some of the bugs present in the current version of the game. Alas it seems producing mead will not be possible till a bug-fix (heh) and hopefully that is one of the priorities for the next update.
Luckily for all us Dwarf Fortress fans, it seems bug crunching will be the focus of development for a while. Some of the new features do seem to work rather nicely, such as grazing for various domestic animals. However if grazing ends up on someones pet, you may have a bit of a problem getting them fed properly. Poor Spearwaved, at least I didn't end up drowning the lot out by accident.
Now I just need to decide if I want to regress to the previous more stable version for purely Fun playing or not. I may just do that as I have some mods I am still tinkering with that could use some more TLC without some of the weird issues in the latest patch perhaps causing problems.
My grand ideas of a ceramic fortress (or one made out of wax) will just have to wait a wee bit longer.
