Relocate bug says insufficient troops


Quite frequently, I have been getting a bug when trying to relocate troops stating "You don't have enough troops"
I have finally been able to intentionally duplicate the bug.
Step #1: Create a large queue of troops to build (i.e. 1200 axes)
Step #2: After some of the troops have finished recruitment, relocate them to another village.
Step #3: After some more troops have finished recruitment, but before the queue itself has completed, try to relocate all the other troops from that have completed. You will then receive the below error.
