While comparing the log file output of the Local Search phase (Tabu) with the final/best solution, there are several instances where log file shows move occurred but the final/best solution obtained after time/user termination shows the planning entity still on previous planning variable.
I saw this issue using 5.3.0 Final and also in 5.4.0CR1.
I saw this issue in my code and also in the "Hospital Bed Planning" examples bundled in the distribution.

Example (Log output from the Hospital Bed Planning testdata01.xml) -
...
2012-04-20 11:53:35,066 [pool-289-thread-1] DEBUG     Step index (27), time spend (22873), score (0hard/-9292soft),     best score (0hard/-9292soft), accepted move size (500) for picked step ([Patient655(11-11) @ Department4_490_1 => Department1_119_0]).
...
Checking the final solution, I see that Patient655 is still on Department4_490_1
