I believe if you edit your original post you can change the title to add [SOLVED] or something to it to indicate it's been solved.

1.12.2 is no longer supported due to age. Please update to a modern version to receive support. See the LTS link at the top of every page for more information.

1.8.9 is no longer support, because it is very very old. Please update to a modern version to receive support. See the LTS link at the top of every page for more information.

I don't know how to be more clear than the instructions I gave

I've experienced this with the latest 1.15.1 build while I was tinkering with making custom mobs, so I went back and used the latest forge without any mods, and compared it to vanilla. I ran vanilla, spawned some cows from eggs in creative mode, flew in the air, and watched them wander around for a few. Did the same with a fresh forge world ( 1.15.1 - 30.0.41 ), and the cows were noticably spinning circles here and there, without any real reason that I could discern, and I did not see that happen with the vanilla cows. Let me know if I can provide you logs or video of it happening, I'd be happy to help any way I can, even if it's to get a working as intended

1.12.2 is no longer supported on the forums. You will need to update to a current version to receive support. See the LTS link at the top of every page for more information.

When I encounter an issue, I search here and on google. 1.8.9 is so old and has not been supported for a while now, there may be threads, but you'll probably have to hunt for them.

Thanks for the primer @Cadiboo, your txt is very very dark in the dark theme tho, hard to read without highlighting it

Start a new thread, and post your logs, rather than necro an old thread from over a year ago. This will help you get more help!

@ObjectHolder(Main.MODID) public class ModEntityTypes{ public static EntityType<UnicornEntity> UNICORN = EntityType.Builder .create(UnicornEntity::new, EntityClassification.CREATURE) .size(5F, 7F) .build("unicorn_entity"); } Do not create your registerable stuff with static initializers. Honestly not 100% sure the reasoning, but everyone that knows what they're doing on here says not to, so I'm sure it's a good reason! You want to build/create your EntityType in the Item registration event, like I had previously said. DO NOT register it. Just create it, and assign it to ModEntityTypes.UNICORN. Then after it has been created, you can create/register your spawn egg within the Item registration event. Then register (no need to build/create) your UNICORN in the EntityType registration event, since it has already been created. If you get a crash after this, post updated code, as well as the crash report. Don't assume the crash report is the same as your original post. Also, please use spoiler tags or an external site (github gist, pastebin, etc) to post your logs so it's not a mile of scrolling to get to the bottom

Please post your build.gradle, my guess would be something wrong in there. Have you edited it?

I believe they call them add-ons, and I'm pretty sure it is nowhere near as flexible as Java edition modding, i.e I don't think you can create new mobs, only modify existing ones. I haven't revisited the capabilities of bedrock add-ons in a while, so this may have changed, but I doubt it.

No prob! I actually just googled "minecraft forge 1.15.1 "Not enough data available"", and the first link was a post on here with that fix.

I would try deleting (after backing up, just in case) the config folder in the game directory.

Please post logs as described in the EAQ. There is not enough information without them to know what is going wrong.

1.12.2 is no longer support on these forums due to age. Update to a modern (1.14.4+) version to receive support here.

Dude don't bump your post after so short a time. This isn't a chat room, it's a forum, when someone that knows about your issue sees the post, they will likely reply. Bumping like this is considered rude!
