Bugs with Shield Imploder, chrystalline tech

Can someone give me some info on the two following bugs (both on stock version 1.66):

First is with shield Imploder. According to description, it should cause damage to the ship by imploding shields.
In practice, any hit from shield imploder removes all shields from the target but cauess no further damage. Is this how it is supposed to work, or is the target ship supposed to take damage when the shields collapse? What is the effect of the weapon damage, if any level hit drops all shields on target?

Second is to do with chrystalline tech and analyzing captured ships. If the ship you capured has higher level chrystalline armor, you can get a tech level from it when analyzing the captured ship (if you have also chrystalline trait), but the tech level goes to wrong tech area. You get a level in Chrystallurgy instead of Chrystallic technology. I assume this is a simple typo in somewhere, as the organic armor analysis works properly if tried.

Can anyone give info on the first one, second is mainly FYI.
