Solved

not sure what happened

Did you clear cache and hard refresh? I've also seen the missing map error, but then it fixed after a hard refresh.

It can be, certainly. Sorry, you guys always seem to be the first to encounter things. I've lost track of the number of times your league discovered an issue.

We have identified that this is potentially memory related, and are looking in to the cause now.

A little update... it is memory related, and it would only happen in a live environment with lots of real people (which is why it wasn't picked up in testing). We've found what is causing it, and have applied a temporary hotfix. All it means is in "profile picture mode" nobody will have a picture for now. This will bring the memory usage under control, until we can patch the underlying cause.

EDIT: There may still be crashes (I just watched 10 laps before getting one) but they should be far less frequent. When we upload a patch they should stop entirely.

Merged the threads on this issue.

Darren will be able to fix it in a couple of hours, sorry for the current state of the web build. Some things which didn't show up in local testing hit the live environment, but because of the nature of updates today we had to put everything live at the same time. There are significant updates to the service all around in preparation for the apps.
