There's no servers that doesn't have any bugs.
You could do as I'm doing right now.. I downloaded a basic TFS source (free version).
And it barely had nothing in it.. really.. moving around character and basic monster/npc was practically everything that was in it.
And I designed and implemented bank/stamina system and much more on my own
And I started this 2 months ago I think.. and today I got a 8.5 source that's nearly flawless (me and some pals are test-playing a few hours every night to try out all systems)
Doing this for some time.. you'll end up having the perfect server
Why aiming at sources that's almost empty? you don't get more than you want, you want a smooth server with everything you want in it. and not a laggy server that have shitloads of "cool features" that you aren't using anyway.
And a tip, you're making custom (this also allpy for real map servers), create your very own data folder.
Add each thing into the datafolder as you create them.. by doing that, you'll have 100% control of the server.. you'll know exactly everything that's in it. and you will become a god of the server =)
