Fellow Kerbonaut Blufor878 found a subtle bug on Forum:

If I launch a Mk 2 Lander Can with a pilot and a scientist, do a Crew Report, and then send the scientist EVA and have him right click the lander can:

• With the standard size Mk 2 Lander Can (2.5m), the scientist can see the "Take Data" option to get the Crew Report out
• With the Mk 2 Lander Can scaled up to 3.75m, the scientist does not see the Crew Report, with no option to "Take Data" in the menu

2.5m Mk2 Lander Can, "Take Data" is a visible option for taking out the Crew Report

3.75m Mk2 Lander Can, "Take Data" is NOT a visible option for taking out the Crew Report

Interesting development!

The problem can disappears under the right circumstances! I'm guessing this is a race condition somewhere (perhaps on KPS-Recall!).

KSP.log and additional data

With the problem happening: KSP.log.zip

I reproduced the problem downto 1.4.3!

ColdJ nailed it! :)

This may due to the center of the craft being further away. The distance from craft is measured from where the center of the craft is in it's .mu model. Bigger craft means you are further away and so outside the distance that is required for it to activate.

Worked out in commit 8fc47bc

I forgot to scale the storageRange attribute!

Fixed on commit 8fc47bc
