no, they sure should get that event! (unless you make a seperate event for concealed players entering)

After all you can always check to have your NPC ignore concealed players afterwards easy enough, but it would be very hard to do vice versa. There may be reasons where you need to also recognize concealed players after all...

Are you sure they are recieving it While the ev.souce is concealed? Should not be from what I am seeing.

core changes.txt

Added : New flag for servspecopt.cfg called "EventVisibilityCoreChecks" set to 0 (disabled) by default.
Enabled - the core does visibility checks before sending events as it did before.
Disabled - requires your scripts do visibility checking.

Check changelog, there is a new option for the servspecopt file for EventVisibility checks. It defaults to 0 (off) for the core. Adding it, and setting it to 1, will re-enable that. RTFM hehehe
