I'm on PS5, just finished the new campaign "Dawn of the Machine", afterwards i was going to check which trophies i missed.....and noticed that the old trophies on the Vanilla Quake which i got completed, platinum included got reset..... I don't remember if the trophies were already reset BEFORE beginning this new episode, but still.....

anyone else got this bug ?

Sometimes the PSN servers desync and forget your trophies. It should resolve itself within a couple hours.
