Each major update, I find most of my visited planets end up ‘reset’, with my discoveries often vanishing or reducing. The milestones remain untouched but the records of the creatures & plants I’ve found are often disrupted.
Fortunately, I’m no longer as dedicated as some & I rarely aim to fully scan any world and typically just scan a few samples. I developed this attitude a long, long time aga when I realised that updates often scrapped the archives, reducing hours of work into digital dust. Now I just scan as required or out of curiosity. The longer I’m there & the more I like it, the more I may scan.
Pity about your world claim. I’ve had that too but again it doesn’t bother me too much. For all I know I’ve done it to others without realising when I’ve gone back through my Discoveries uploading backlogged finds.
