[BUG] Issue when blocker ends jam in box and there is no pivot in next jam

[JonObst]

Describe the bug
Blocker in box between jams when no pivot fielded in next jam causes the box status to be applied to the incorrect blocker.

To Reproduce
A jam happens, and the first blocker in the lineup sheet is in the box when the jam ends.
The team then does not field a pivot in the next jam.
The ePLT then begins entering the lineup, and assigns three new blockers (leaving the original blocker from the previous jam in the lineup).
The blocker in the box is moved over to the second column (pivot) in the lineups
The first blocker in the lineups is now shown as starting the jam in the penalty box.
Clicking on the dash will show the correct that blocker sat in the previous jam.

Expected behavior
Original blocker should retain the in-box status

To further complicate things, the penalty shows as served in some places, but not in others.

At jam start the skater who was in the box is not in the lineup and the pivot spot is empty. The blocker is only entered half a minute into the jam. I can only reproduce this by marking the blocker on the bench manually. So my guess is that the ePLT did this by accident without noticing it. (It is a known issue that entering a 4th blocker will initially mark them as a pivot, which would explain the ePLT's memory of the blocker being in the pivot column when they shouldn't have been.)
(I can't fully confirm the sequence of events due to lineups being hidden outside of the jam. But unless someone can give me exact steps to reproduce this in another way, this is what I assume happened.)

CRG 2027 will have a confirmation popup when a blocker in the box is moved to a different position, including to the bench, which should resolve this issue.

(And I will have another stab at that known issue. But I have failed to find the source of the problem at least once in the past.)
