Well I didn't REALLY have any to reassign either
But, I did have three on lighting and my 'plan' was to take one off - just to test the functionality / cost / any bugs and then put it back on...
But since it pulls ALL the points off for the one price to allow reassignment (keeping in mind this is test - this COULD change) I just put the points 'mostly back' to where they were.
Today I'll visit again, and see what the cost is
