Same happened to Troubling Times, (once) but according to... someone* ... Llama(beast or server) added 24 hours during the patching to 3.26, so that was allegedly normal behaviour.
Server status:
"Last updated at 21:15 GMT on Sunday January 30th.
Current time: 10:04 GMT
"
Does this 13h diff make sense?- Or is the server in distress?
