While in battlescape, Aliens' turn (or civilians' turn) does not end, and mouse pointer still looks like a sandglass. It often occurs, but I cannot tell how to reproduce it with 100% accuracy.

My conf. :
* Windows XP - Family Edition
* game version : v2.5-dev, nightly 18/05/2013 (I never noticed this problem with latest stable v2.4.)
* Athlon - XP100
* Nvidia - GeForce FX5200 (latest drivers installed)
* 1 Go Ram
* Not connected to internet (and then: playing a one player campaign)

The zipped attached file contains logs, screenshots, conf, and quicksave files made while trying while trying to identify the problem.
* "Mission 1" repository was made while activating/disabling music
** "No problem" repository contains files that show no odd behaviour: I could finish the mission without any problem
** "Problem (2nd try)" repository contains files where I tried twice to end the mission: firt time = no problem, but second time = "neverendind alien's turn" problem

* "Mission 2" repository was made while changing game language (french -> no language); it contains 2 repositories that showed the bug, with both settings
