• Ladders for race events now persist forever after the event has ended.

Will this help in creating some kind of ladder ladder? Something that gives points to people based on how they finish, and if so will you be able to allocate points retroactively starting at OB?

;)

Haha! That was great.

Also, I like all the changes! Top 25 death messages seems like a very good idea!

Nvm. My Bad, all workin good now.

improvements on the side of Desync?

Out of curiosity, can we hear any details about what was causing the realm crash?

It boiled down to a function like this.

///Returns negative number if a < b, positive if a > b and 0 if a == b
int compare( unsigned a, unsigned b )
{
return a - b;
}

See if you can spot the bug. I can tell you though that the effects that it had on the realm were very hard to correlate back to this bit of code.

Hmm, well it's returning an integer, which isn't specified whether it's signed or unsigned. If you have two very large unsigned numbers, and the one is negative and being subtracted from a positive, you could get a number larger than what a signed integer can hold? That would be my guess. The result would be an unsigned number being converted into a singed one, which could result in a realm crash if a function didn't expect a certain kind of comparison.

How about having death notes for anyone that dies over a certain lvl threshold? (like 80+)

Would like to see something along those lines for longer duration ladders.

I probably shouldn't doubt you guys, but I'm quite wary of this. LotRO did the same thing with their PvP Ladder system, the conclusion was - when faced with a large amount of players - a bottleneck of information trying to hit the client server all at once, thus resulting in some pretty bad lag issues and crashes. They then went on to include this in their MyLotro "armory" system for everything, which made it even worse. Granted it's taking it from a 3min to a 30s time frame, gotta wonder if this will be too much information for the server to process in that time span, especially as the game continues to grow.

a - b > max(int) which overflowed and made a terrifically huge negative number. The side effect being that a was much bigger than b, but the comparison reported it as being much smaller than b. Or vice versa.
