V124.0 and maybe before: message list overflows

[FLN]

Particularly in multiplayer games, it becomes obvious, that the message list overflows.
I mean, after a certain date/amount of messages the list will no longer hold new entries between sessions.

While a session takes place, the list get's updated as normal, but after leaving the game and returning later, all future messages after this certain point are lost and won't be shown in the list anymore.
(I guess it might have a similar cause like the "bug" with the chat history overflowing, July/August last year. Though I wasn't able to find the concerning bug report anymore.)
