So that's one that, when we figure it out, is fixable by hotfix? Some things require a patch, some things require a hotfix.
TL;DRServer-side code changes can be hotfixed if they involve no data or asset changes and keep network compatibility, while other fixes wait for patch windows and hybrid fixes are hard because restarts disconnect everyone on a shard.
I can speak a bit about the hotfix, how it works, right? Now, I don't like to use the word hotfix for everything, but that's the word we have for now, right? Because not all fixes are necessarily hotfixes. Some of them just need to go out. But so what we can fix right now is a server change. So a change that goes on the game servers. That's one of the easiest things to roll out. So we can actually make a code change, and then we start deploying it, and then your game servers will slowly start updating, right? And that is the easiest one to roll out. But there's some requirements for this. There must be no data change, no asset change, and the network compatibility of the build needs to be maintained. And so that means that there are some things we cannot hotfix because it would cause a client incompatibility. And so there are some bugs that we're like, we have a fix. We can't roll it out, right? We have to wait for the next patch window. Which we are talking about, in the interest of this, to have now maintenance windows where we can actually roll out data fixes, right? Where we now need to force players to upgrade their client, but that would allow us to actually take the environment down, also do some maintenance. We rarely do live maintenance on the environment just to change things. We kind of try to keep them the way they are, but this will allow us to actually... So we're trying to nail the process now for that. And so the second kind of thing we can change is a hybrid fix. Now those are very hard to do, because a hybrid restart will disconnect all players on a shard. And so we can't upgrade a shard that's already running. And we have much fewer game shards now than before. And so that means that disrupting them will have a drastic effect on the live environment. And so those fixes are a bit of a problem. So typically it reflects in the number and the name of your shard when the hotfixes roll out.
