The "metal flowers" issue still exists.
Once you pick up a single metal flower with the gathering boost option enabled, you can never pick up another metal flower.
Somehow special collectible items like metal flowers need to be excluded from the gathering boost cheat.
Then just turn it off before you pick them up if you know it's going to happen. It's not really an issue if you know it's going to do that and there is a way to prevent it.
First off, I have to say thanks for the updated trainer. Sterling work, as always guys. However, it seems that the Unlimited Health option now applies to enemies as well. Also, Ghost Hunter Mode now sets your health to 200 and makes the enemies invincible.
PM Caliber and let him know.
