After some basic testing I think you are recursively searching alive dinos to determine which classes to populate the list with. Only problem this can be a bit misleading to a server with custom spawns where there might only be 1 or 2 of a particularly rare class alive at a given moment and several minutes to several hours could pass between when those 1-2 dinos are killed and they respawn. Providing a button that allows you to search any class regardless of whether it is detected alive or not might aid admins / users in situations where they are searching to determind if something rare has spawned yet or not. I hope this was clear and if you have questions feel free to ask away. P.S. I know you get this all the time but I love the mod. Great job and keep it up, easily one of the best mods available for what it does. In some ways though I'd love it even more if it restricted its capabilities based on whether a standard user was using it versus an admin. Perhaps some additional restrictions configurable in an ini are in order? I'd donate to see that happen for sure.

The problem with such modded creature is how they spawn. If the modder uses regular spawner or remapping all is fine. But a creature can be spawned by a simple SpawnActor command. There is no way in the Ark dev kit to find out what subclasses of the PrimalCharacterClass exist.
If i had designed a dev kit, i had implemented a registration system for creatures. Each mod had to register a new creature class. But this does not exist, and the only way is to scan the world for new spawned creature classes. And if the creature dies, its actor gets destroyed and there is no way to check for this class.

You make an interesting point about the modding system and creatures that mod makers create. I was however referring to creatures that are a part of the base ARK game. For example my communities current map playthrough is on extinction however extinction doesn't have certain creatures we've deemed desirable to play with. So in that respect we've decided to add a few creatures commonly found on other base ARK and DLC Ark maps like the griffin by adding their spawn overrides in the game.ini.

Any thoughts on this? Sorry for my lack of clarification, I posted rather early / late this morning and was likely not coherent.

EDIT:
It would appear after some time your mod did in fact pick up these added creatures and allow us to search them. Is there some time frame for the mod to detect new creatures added to the spawn? I know your next statement might involve something to the effect of "destroywilddinos" however we do that at each server start... Might that be causing your mod to take longer to bring up a more accurate listing of all the dinos on the map?

@Deth Sevin when you start Ark the mod tries to find all creatures classes in the game files, that can contain the data for spawning in dinos (there are several sources, which can contain dino references). This contains of course your remapped dinos, because these datas are accessible through the mod. But there are exceptions like the alpha creatures, which are spawned after the whole map is loaded and after the mod has done it's initialization.
because of this, and those creatures which are also spawned by other ways, i have implemented a refresh button in the last update.
You can always search for any creature using the "Any Creature" selection and a search phrase like "alpha".
You see, Ark modding is not so easy, because we, the modder, had to check for obviously simple things and we need to handle this by building workarounds.

Thanks a lot for explaining that implementation of the refresh button, makes sense now that I've used it a few times.. And since you've been so attentive to your community, you deserve a free meal on me. Thanks for being one of the good mod developers. FYI Might want to put a Donate PayPal Link Button in English as well to make it easier on your English speaking fans.
