Problem with completing an achievement “Enlightened” PS5

My problem is that I’ve completed every achievement in the game except one — collecting all the plants in the garden. I don’t have any issues with the achievement itself, but I do have serious questions about how often new plants can actually be obtained.I have fully completed every location in the game at least 10 times each. I currently have 92 hours played, and I still haven’t finished this achievement. Do you honestly consider this normal or acceptable?This isn’t some extremely difficult game where a single achievement should take this long because of pure randomness. At this point, the game is no longer enjoyable for me. I just want to get the final achievement, and the only reason I keep launching the game is because I’ve already invested 92 hours into it.Can you please explain what is going on? Is this some kind of bug, broken drop rate, or another issue?
