Thanks. Does this bug make that initial unlock process harder?
As Stormy mentioned, you don't need the wreckage components for the Guardian FSD booster and you can see what's needed for the various modules here

To put things in perspective though, it has taken me a week to collect all of the Guardian specific materials for all of the Guardian modules starting from scratch. So there's definitely something wrong with the drop rate for the wreckage components but overall it wasn't a disaster as by the time I had collected all of the other Guardian materials I was only short of six wreckage components and had to do a couple more runs to get those.
