Bug - Ingame "Kill Log"
Something I find annoying is the glitchy "Kill Log," where you see who killed who while you play in a server. I find that a lot of the time, I'll either receive two copies of a message, none at all, or it appears extremely late. It seems like it's been made overly complicated and thus buggy.

It's sometimes hard to catch who killed who in the kill log when it fades away so fast, the messages should stay longer.

Bug - Chat Log "Overflow"
When people have been typing a lot of messages into the ingame chat log, of course it will fill up the little list they go into. The problem is, when someone then sends a message that contains more than 1 line, and it's added to the already full chat log, the chat log will only bump up 1 space when there has been two lines of text added. The result is that the second line of text is sticking out of the bottom of the chat log, and overlapping the actual part you type the messages into.
