Well, that is interesting.

It _seems_ that the bug I’m chasing could well be related to the “Failed to construct Notification” error.

**IF** that is the case, I believe that the only place where this piece of code (`new Notification`) appears is in core Discourse. So it _could_ be a bug in core.

That said, I’m sure more people would be reporting it if this was a problem with core Discourse. So it’s more likely a plugin issue that is breaking core.

Can I ask what non-Discourse plugins you have installed? Let’s see if we can find some common potential cause outside of core.

I don’t have much data on the “Failed to construct” issue at the moment, but what data I have points to a small group of users/devices that are causing the errors.

@thefreekick, how about you?

Do you see anything like the same bug that we’re discussing here?
