I hopped in for a bit and the servers were still stable.

We had over 500 players in the shard. I travelled from Pyro to Stanton and everything went fine.

Server FPS was stable at 27.

Some players were still getting caught by the bugs listed out in the bug avoidance thread. Specifically the quantum refuel issue.

Wakapedia-CIG listed out some of the fixes that have been addressed by the Hotfix and this maintenance:

Client

► Fixes for multiple client crashes

► Fix for an issue causing FPS AI to attack downed player corpses instead of the alive players

Server

► Fixes multiple DGS crashes

► Updates to resolve multiple Align and Mine Blocking Issues

► Updates to stop some Align and Mine Exploits

► Fixed an issue causing several medical rooms to be missing from Landing Zone Clinics

Hybrid

► Fixes to massively reduce high hybrid-service pings causing multiple interaction delay and other issues

► Fixes for multiple hybrid-service crashes

► Further updates to help reduce players getting stuck with long load times in the PU

► Updates to help stop players getting stuck with an “Invalid Location ID” black screen upon death
