Specifically with the binding trait (eg as resoln) it appears that the techs that unlock the various improvements to shard altars, etc don't unlock any buildings. (As far as I can tell they do actually unlock fine, at least as far as I've played I can build them and get eg crow demons fine.)

Poking around in the data files it appears that this may be because the resoln versions of these buildings are seperate buildings with the extra summoning ability, which replace the basic version if you have the Binding trait. The only notable difference I could see is that the resoln versions have a HideInHiergamenon trait, which might as a side effect make it not appear in the tech tree, although removing it probably would cause other problems (redundant shrines in the hiergamenon with the same name, I'd assume)

(I'm not sure if this has been reported or not already; I didn't see anything about it; also I'm not quite sure how I'm supposed to name these threads and there didn't appear to be a faq for bug reporting so ummmm sorry in advance if this has already been done or I named it wrong or something.)
