Double message when trying to talk to Tip when he's not there

[eriktorbjorn]

>LOOK
(west part)
You're in the west part of your laboratory, next to a shelf full of mechanical
supplies.

>ASK TIP ABOUT CAPSULE
Tip Randall isn't close enough to hear you.
Sorry, but Tip Randall isn't close enough to hear you.

>ASK TIP ABOUT TRAITOR
Tip Randall isn't close enough to hear you.
You wouldn't find any traitor there.

>ASK TIP ABOUT ME
Sorry, but Tip Randall isn't close enough to hear you.

So there isn't a double message in every case. I don't know what's causing this.

Using the game's built-in #DBG command, this is what I get:

>#DBG
Find them bugs, boss!

>ASK TIP ABOUT CAPSULE
[Perform: 18/Tip Randall(gl)/that thing]
[Not Here: Tip Randall isn't close enough to hear you.
[Found 1 objects]
[Namely: catalyst capsule]
Not handled]
[yourself=][Actor: Not handled]
[Room (M-BEG): Not handled]
[Preaction: Sorry, but Tip Randall isn't close enough to hear you.

[Room (M-END): Not handled]

>ASK TIP ABOUT TRAITOR
[Perform: 18/Tip Randall(gl)/that thing]
[Not Here: Tip Randall isn't close enough to hear you.
[Found 0 objects]

>ASK TIP ABOUT ME

[yourself=][Actor: Not handled]
[Room (M-BEG): Not handled]

I'm not sure how much help that is.
