Well, you can go out and make an installer for every tiny patch. Make people have to download every tiny incremental installer and put that over their current build.  Or maybe even go to all the effort to make a full installer, get people to upload it to mirrors and get players to download it every time a tiny patch fixing one or two problems is released.

We are the only mod using one because we are the only mod releasing, or planning to release so much new stuff over a longer period, instead of packaging a load of it up at once, we are striving to keep the mod interesting and make it always feel new.  We are a mod who knew that Client auto updaters also requires server autoupdaters, and the only mod to have a person clever enough to make both of these.  We had a mod team who was realistic, knew there would be bugs in the public version because there simply isn't enough testers for a large scale testing session to find out about some of the things we missed, and have this as an easy way of fixing those problems once they are discovered. 

We are possibly the only mod to actually THINK of having an autopatcher. I don't recall any other mod teams for the Battlefield series talking about making and distributing an autopatcher.  I bet a few other mods will end up using exactly or a very similar system that we have in place right now.  Other mod teams never thought of or never had the ability to make a launcher, thats the only reason we are the only mod to have one.

What floors, what buildings and what glitches?  I haven't seen a report of any of these things in the Bug Reports forum.  How people expect these things to be fixed when they don't actually say WHAT needs fixed is beyond me.
