Fix pickup slot display
Closes #215 (closed)
What does this MR do?
I had removed a line  that looked like it was just an assignment to an unused variable. What I had not noticed is that the
getAbholdates method has side effects (it adds stuff to
$g_data which is read later).
How confident are you it won't break things if deployed?
Very, it's a simple revert of one line.
