Going through some of my DMs tonight to check on something, only to discover that messages I received the past week there, then a gap of 3 weeks missing, that means early January. Then a sizeable gap from Mid December to September is missing. Only messages from Beginning of September back are there.

I didn't delete them, where they go?

Anybody else experience the similar event?

Kinda sucks, there were communications I needed to check Refs on, certain folks asking/answering questions i needed to maintain.
