By the way, nightwing attacks on my (just embarked, sinister fortress) surface herd of goats are now repelled by the pastured nearby tortoises zerg rushing the nightwing and breaking every bone in their body, pinning it down for the dwarf with the axe to come along and finish it. I'm pretty sure tortoises don't have [LIKES_FIGHTING] or whatever.
Clearly you brought along the teenage mutant ninja turtles.
Can we get a rare ninja tortoise caste, akin to the special operations pigeon caste?
That. Is. Awesome.
Tortoises in LFR are quite large, about twice the size of a full-grown human once they reach maturity. They are also, however, docile and slow. If they land a lucky incapacitating early strike, they can defend themselves, but they won't get many attacks in on their own. But, as you have witnessed, numbers are a powerful thing in DF.
An update on the reported issues. Bog trolls are being created in world gen, and are sometimes surviving. If you embark within the first 200 years or so, they're almost always there, but in longer histories without extremely abundant civilizations, they are dying out a little bit more often than other races. This is something I will look into a fix for.
Magma alchemy labs and casters are not showing anything in the errorlogs, but are not always recognizing the reagents for their reactions as present. Results have been mixed. While this is relatively meaningless for precision tools, which don't require fuel anyway, it is something that I need to take a deeper look at to determine what exactly is causing the problem and if the problem is on my end or a hangup with DF itself.
