Beaver.
Using the new client:
http://beta.vortexwars.com/I came to the realisation when I was spectating a match.
When you to through the history of what was said in the chat log,
It goes back to maybe 4-5 lines of text then abruptly stops.
I don;t know if it was a issue on my end or not but, letting you know anyway.
EDIT:
I think I just saw you "Test" xD
Its weird, It was doing it in the other game, maybe it was a fluke.
Thanks for checking it out though.
