Its almost as if... we can't help you... if we don't know what you're talking about... All published versions save for a handful of derps work just fine. Post your logs. Also, we only support 1.14+ on this forum so we won't help with older things.

The colors are.. odd.. they need to be updated to look better on the Mojang background. However, Honestly I think that someone should come along and make a function to render strings with an outline. Because white text, with black outline looks great on all colors. But ya, as Dies said, as it sits the new early loading screen is a complete re-write, so it doesn't have the splash.properties that used to exist. Feel free to work on making it better.

As I said, this has NOTHING to do with Forge's code or how we build the classpath. We could technically put the jar whever the hell we want. This is wholy issues with SERVER HOSTS and other users. And the drama/bitching that will come from it. This is just a case of... don't be dumb and run the vanilla server... Unfortunately there isn't anything we can do to mark the world as not loadable by the vanilla jar. As it's not code we control so there isn't any way to add protections into it. Many Many external things can corrupt your world.

This is fundamentally false. Just because a recipe uses a item doesn't mean that that item will trigger the recipe to be unlocked. The mods/data packs must add advancements/triggers to unlock them.

You have been warned twice in this thread to speak English. Yelling at our mods in another language isn't going to help that situation. If you want help on this forum, use English.

IClassTransformer Is by definition a coremod. Try making the mod without it and see if you can use the mechanics of Vanilla/Forge. Just because you did it one way in the past doesn't mean you have to do it this way forever.

The jar IS a program you can run. Open it with java not whatever you're opening it with. https://johann.loefflmann.net/en/software/jarfix/index.html

... You need to run the data run config, not the client/server. This is a in dev only event.

Hash codes are explicitly NOT guaranteed unique. that's why equals exists and is tied to hashCode. think about it, how would you shove 96 bits of information (3 ints) into 32 bits (1 int) hash code uniquely? literally impossible. The standard practice is to try and spread out the hash codes when you can to spread out the collisions. Which is typically implemented by multiplying intermediate hash codes by some prime number. In this case 31. And no there is not 31k possible values for a vec3i hash code. there are 2^32 possibilities.
