S-T-H just pointed out to me that the JP 360 site's post maintenance notes for this past update included a small mention of the current run of GBR being extended by a week. Now the event is scheduled to conclude when the servers go down for maintenance on January 15.
Also, there was a bug fix in Scarred Planet. In block 3, enemies would get stuck in rubble while attacking, making it impossible for them to escape. And finally, compensation is being considered for the second rollback that the 360 side received. It has not been confirmed if there will or will not be compensation for it, but whatever the decision, it will be posted on the JP site.
