Unfortunately, getting the issues addressed and tested in Umbara is taking longer than expected. As much as we want to get Crisis on Umbara to you ASAP, we want to ensure that it is at a quality level we are comfortable with. For that reason, we need to delay Game Update 5.4 by an additional 24 hours.
The new maintenance window for 5.4 will be Thursday, 8/24 at 5AM PDT. I will go ahead and update this timing in all maintenance messaging as well. We do apologize for the delay and thank you again for your patience!
