I found 3 bugs; One is private messaging on the new HD client. You can't see it in blue righting above the chat box when the split chat is turned on. But when it's turned off you can see it in the actual chat. This needs to be fixed ASAP.

I found this bug when I got a level. This happens with all levels in all 508 clients. Needs to be fixed and say the real level and make it show that you get a skillcape from vannaka when you reach 135 in the skill. We also need to make it so it shows the xp until the level in the client.

When I reached 125 Attack.
I also found that when an interface shows on the new Blitz HD client it is invisible and text is black and hard to read.
