Ok, so it were the Earthborn boots that didn't give you Phantom Dash? Not a bug, just Earthborn gear?
I see this quite often, people complaining about not getting mods from disassembling items, but then it turns out it was the DLC Earthborn gear.
u/thearcan maybe something could be done to avoid these in the future? Either make the DLC items give us mods or put a clearly visible disclaimer somewhere that disassembling Earthborn gear does not give us anything.
The Earthborn gear provides a set of higher Tier mods that would normally only be unlocked further down the story campaign. To enable these DLC items to grant the mods upon dismantling them could very well unbalance the early story campaign for players who have purchased this DLC. That is why the mods they provide do not get added to the library.
