This is why I rarely bother with the forum anymore. It just does as it pleases.

I think the messages still get sent, but it no longer bothers to notify people & the message order is probably not in the correct order either, at least that's what happened to me last time someone sent me a message - only knew I got one because I had email notifications enabled, I wouldn't have known otherwise.
I would recommend using our discord server if you aren't already on it. Most of the regulars are online on there most of the time already, including me, Simon, & Sebastian.
