Round Robin didn't follow Public Group Index Order

[djmsharpe]

First of all, thanks for building this! Huge timesaver!

My public group has 5 Members:

Index 0 - User A
Index 1 - User B
Index 2 - User C
Index 3 - User D
Index 4 - User E

The Round Robin Assigner just assigned the first opportunity to User E, the second opportunity to User B and the third opportunity to User C. I'm really confused because the custom setting clearly followed the index 0-2, but didn't assign the opportunities in the correct order, Users A-C.

I created a bunch of test opportunities and the succeeding opportunities we're assigned in the correct order: Index 0-4, Users A-E.

The sales manager want's me to find out what caused the first 3 opportunities to not follow the correct order and I can't explain it. I've turned off our old assignment flow and I'm also updating a new custom field created specifically for this round robin assignment so I know they didn't overlap. Any ingishts?
