I'd still like a Dev comment on this one. We're building characters here. Especially skill points that can't be re-specified, we deserve an answer on whether the change is a bug, intentional or what.
Again, from the User Guide based on original code:
"Trapfinding Feat: Defensive - Traps. Rogues can use Search skill to locate traps when the trap has a Difficulty Class higher than 20. Recieved level 1."
The original Rogue Trapfinding Feat had nothing to do with Spot.
