Agreed, perception checks are frustrating. Also had a chest that was trapped, perception check succeeded, but never figured a way to disarm the chest and it never showed that the chest was trapped so maybe a assumption on my part, but the perception check came after it was lockpicked. Definitely need to make successful checks a persistent highlight.
The one in the cave where the four goblins are torturing the druid? It doesn't seem to be a way to undo that trap without using the key.
