Well, this is very strange to me. But, after my install of vista, i downloaded blockland again (No i didnt back it up, there goes my hard work on TDM's :C) and noticed, that when i look at any player, in-game or not, the player's datablock appears to be messed up, here's an image:

That's exactly what it looks like in-game, also, and i just fixed my hosting too...
Any help?
