Only one effect need other effect to be found. Different effects can require special actions (like solving puzzles) or not.

ah ok. Just making sure that base effects is not included in the count. I already tried hard to find the other two effects and revisited the other areas again.... I couldn't find it.
EDIT: I have found one more in the black door, just I dunno where else to check the remaining one, I feel like I already have checked everything at this point... unless there's one again in a game breaking bug state.
Maybe random i made is too harsh or you were unlucky.
Dandelion - White World random event (In the beginning route there is a small field without anything. The statue will appear)
Lily - Town Apartments random event (Before elevator room. When you go up stairs instead of elevator you will found yourself in green room)
I guess the dandelion still in sense at least. (and found it before, didn't know it's another area. Tho ynfgs, are about dreams with variety of themes and topics, and I guess randomness, I guess the elevator one would require a bit of like even a miniscule hint, but again everyone I guess will still see these comments now. And I also had a feeling my suggestion could ruin about that, so don't take it much, and I'm sorry for randomly broughting it up. Tbh I thought the effect will be in the actual one other room for the lily.
I guess time for the bugs I found and/or other potential forgot to make the event temporary and things. Still take your time and don't overwork.
1. The one effect that requires another has a missing sprite. Trying to go in and go out freezes the game.
2. Same thing for the return to nexus bench in black door chance effect. If you try to go further to the right. It goes back to the white bg void and freezes the game.
3. If you kill the one npc with the one random chance event of being nothing. If they're there and killed before, they are stuck in the wall and never going back in the room. I had that save permanent.
4. Tho this might not be a bug, but killing the moon event is permanent, and doesn't go back to its former state even after waking up. Sprite also goes to hole, but you can still enter it and it's still the black moon.
That's all the bugs I found atm. Sorry couldn't provide the video/playthrough follow up for at least the bug checks, and I'm unsure if there are more that I missed that is permanently gone. But yeah that's all I can provide for now. Still a pretty neat game again now after finding all effects. I hope to see more of it later.
Due to long reply I will reply it here. I like the puzzle mechanics of some effects and I think that's one thing I will praise about this game's effect hunting mechanics.
EDIT: Just a follow-up of like the playthrough part 2 is out, and I kept the bugs in the video unedited, just for more clarification. Tho the other bugs, I didn't perform, since I was recording. I just hope the previous comment and that will help.
