Fatal exception while saving, but also the popup for that not working correctly

[Ashe]

I got a fatal exception while saving presumably shortly after the attached save going down through spiral bored zones, but also, when the popup came up for it, it was alongside whatever other menus I was interfacing with. The controls menu popped up for an instant, and then when I used look at a nearby clone of saad amus, the look got stuck on them and I couldn’t do anything while the popup also remained, so I alt+f4’d.

It happened again when spiral boring: the popup can be closed by clicking it with mouse but does weird things with keyboard. It triggers from the game trying to save when going down

[Ashe]

found the culprit LOL
I tried cleaning out HighScores as per #5723 but that wasn’t the problem this time, it’s an event pool size issue

from moment above

also just realised the highscores was in synced now and I hadn’t actually tested that I just deleted the old one, but I confirmed just now that that’s definitely not the problem. Error from the log is:

The game only fusses while they live, afterwards all is well it seems.
