Aisu, I am not going to be able to resolve this bug immediately. I have looked at it and diagnosed it and know where the issue lies, however to change the algorithm tonight would take too long and would leave my system unstable for tomorrow. For now, the next update will include a workaround, and will force the system to replace all dots in user names with underscores (as it does for other characters). I do have something of an update though. Before I post this I will apologise now for filling up your memory cards. http://liqbase.net/#images This will be included in the released version in a couple of days.
