Regarding server stability:
Along with BWL, a lot of fixes / new systems have been applied. You can find some on the above patchnote. Others are more "internal" changes, like a new tickets handling system that will greatly improve GMs productivity, and their ability to handle tickets from different realms more easily.
We noticed that these changes globally affected server stability, by introducing crash sources.

Some technical information regarding how we fix crashes
When a crash happens, we always get information regarding the faulty code. Generally, we can deduce the cause, and fix it within a day.
However, this update introduced a crash we could not easily track, because a faulty instruction would corrupt memory, and produce a crash when another part of the server would access this memory in another context. To identify these crashes, we need to monitor all the memory reads / writes, and to make wrong memory usage crash the server instantly (instead of having a possible crash somewhere else later).

What we did
Once we identified that a monitoring was needed to fix this crash, we had to find a way to monitor code errors that could run with 5000 online players (high performance required). This monitoring has been implemented on the live server during short periods of time.
In total, we got 60 crashes caused by memory errors; all these errors have been fixed now.
25 core fixes and 10 scripting fixes were needed.
We fixed additional issues by running these same tools on development server by simulating high population conditions.

The result
We will continue monitoring the server to see if the crashes are still occuring after the fixes we made, and after this update. Our main focus, in the dev team, is to fix the crashes as soon as possible. We will take all the possible actions to restore the server stability before the end of the week, even if we have to temporarily limit population, impact server performance, etc ...

For the future
In order to prevent this from happening in the future, a procedure has been designed to detect these crashes in early development cycles.

Well done on AV fixes! <3 I was honestly hating it.

It still has imbalance issues if you didn't fix that. Quartermaster NPCs are offensive, they should be passive and fight only when attacked. In addition, they respawn wayyy too fast, making an endless delay against horde forces as horde is forced to aggro them even till the aid station flag, while the alliance loses aggro halfway towards the relief hut flag!

Please investigate this!
Was good to have you all
