Personal messages don't come through even though they appear sent

Around this time I chatted with chartreuse in pms. And I felt some messages from them were missing, and we figured out that indeed the messages chart sent appeared on their end but not on mine. Reloading the page on my side did nothing. Reloading the page on chart’s side cleared broken messages.

Conclusion: pms sometimes bork so if you send valuable message reload the page to see that it’s gone through.
