Greetings,
Thank you for your report. However, it seems to be working as intended.
The purge system works with several validations to raise the bar, one of them is whether the player (or one clan member) is online on the server. If online you (or the clan) get a positive check, when you’re not you get a negative point which decreases the bar size. Therefore, if you spend more time offline than online, your purge bar is unlikely to raise enough to activate the purge.
