Hi! I think it is too easy to find all memory modules now. I think players should not have leader buff effect if they do not have same memory module as leader.
I mean if leader tern on memory module and his team mates do not have it they should not get any buff effects from that module. After that no one will throw modules like garbage in the dungeons. I do not know if it is real to add that in game, but it can increase the relevance of memory modules.
