I know you're assuaged after reading Leandro's twitter, but I'd like to clarify this a bit for others, according to my understanding.
The *I24 source code* is widely public now. That, however, is not enough to run a server or a client (btw both server and client code are packed *together*). As far as I know, several types of asset files are also needed, and those are not yet properly publicly available.
What was running on this Discord server, was a *precompiled* I25 (I24 + Leandro's and his team's modifications) server (aka binaries), joined by the I25 client supplied through Tequila. Again, as far as I know, Leandro was in the process of releasing the I25 source code but it had to be scrubbed of any privately identifying information before being made public.
Why the I24 assets, or the I25 binaries and assets aren't publicly released at this point, I do not know.
From my reading of the last 10 days of news and forum posts (including here):
-- Issue 25 in binary form is ready to go now. It's the fastest route to go live immediately, and the COH Discord team is fine with that for now, but they want Issue 24. Before Leo can release this source code, he needs to scrub it for anything that would tip off investigators to the identities of who modified it, both NCSoft staff as well as SCORE (doesn't take a lot of guesses as to why both of those matter). That'll take some time.
-- Issue 25 source code will be possible, but not immediately. This can be distributed in Source Code form, but it must be scrubbed before release. (See above)
-- Issue 24 will be possible AFTER the Issue 25 source code is scrubbed. This is manually rolling back the changes Leo made to Issue 25 to put it back to Issue 24, then adjusting the server configuration and databases to work with the rollback. This will take a few months and may be as late as this Fall, depending on his schedule.
Ultimately, public servers will have their choice of what resources to use, but they'll need one or the other. The source code by itself without these resources do nothing. If you want Issue 24, you'll need to wait. If you want to play ASAP, Issue 25 is what's on the menu.
Hopefully that explains why Leo's Twitter posts are essential to the team: they need his binaries to get a server online as soon as possible.
