edit: case solved
it was the setting of what type of an item to search. I changed it to search all and now I can see all the BPCs.
There used to be so many different blueprint copies, I mean battlecruiser and battleship BPCs.
They were really saving isk because what’s the point of a 600mil BPO and researching it by myself when I can get a 10/20 BPC for even under a million. I have never even made 600 of the same ship.
My interests went elsewhere for some time but I check it lately every now and then and the market is dead? For every larger ship it appears?
Do I have some sort of error? My search settings appear to be correct, I even widened the search to low and nullsec.
Some people even used to say in the past they make more with selling BPCs than actual ships.
Can you search completed public contracts for the BPCs you’re looking for? Then maybe reach out to that character telling them what you’re looking for?
