Can't increase clan Tier eventhough the event is finished.

[Tuho]

Hey all, I thought about posting this here might be the best of choice.

As the title says I can't upgrade / increase the clan tier eventhough the halloween event is finished.

It keeps saying that the time-attack is still ongoing.

Does this mean that either people are still in the mission? or that DE hasn't enabled / disabled the "function" ?

 

Any advice would be welcome.

 

ps.

Reboot of warframe has been attempted.
Relog has been attempted.
Several Warlords have tried it as well.
