holograms fall to the floor

[HeberonYT]

I have a strange problem when creating a hologram.
for some reason, they are affected by gravity, no matter where you place them.

spongeforge-1.12.2-2768-7.1.5.jar
holograms-3.2.0.jar
Modpack: Project Ozone 3 (v.PO3-3.0.38)

I can't reproduce that, please try on a fresh server with only Sponge and Holograms installed.

[HeberonYT]

It seems that it is a mod included in Project Ozone 3. With sponge there is not this problem.

[randombyte-developer]

Uh, they include a huge list of mods. Maybe they can guess what's going on: https://github.com/Cazadorsniper/PO3/issues

Basically the gravity NBT of armorstands doesn't work.

Btw, can you please post the whole server log?

Hello! I've the same issue on Project Ozone 3, and now on FTB Sky Odyssey as well. Here is some proof to show what happens. Another plugin that uses Holograms called HuskyCrates was effected by it as well.

Crate hologram is falling: Crate hologram
Normal hologram is falling: Hologram

Spectator mode view: 'Flying'
Spectator mode view 2: On the ground

Here is our latest server log from FTB Sky Odyssey: Server log

It started happening on Project Ozone 3 after we moved server hardware and updated the modpack from version 3.0.37 to 3.0.38 (changelog). Sky Odyssey started happening since the first time we got that server up. The Sponge versions work perfect, and I use the same version on other modpacks which work. I assume a modpack change or mod might be the cause of this. I doubt any plugin as the plugins on all our servers are the same.

If there is any more information that you need, I'm willing to open my server to you so you can take a look yourself and test. Not sure if this falls below advertising, but you can join our discord by clicking here. You can contact NLBlacky (me) if you want to test on our server. I would like to have this issue solved :)

[NLBlacky]

I might have found the cause of it but I'll need to do some testing with this.

Only main change beside mod updates in Project Ozone 3 is that ProjectEX has been added.
ProjectEX is also part of FTB Sky Odyssey, but beside Stoneblock 2, not on any of our servers.
Stoneblock 2 however does not have any issues with holograms so I'll post the versions below since it might have happened between the versions:

Stoneblock 2: ProjectEX-1.0.0.10.jar
Project Ozone 3: ProjectEX-1.0.0.13.jar
FTB Sky Odyssey: ProjectEX-1.1.0.14.jar

Edit: Disabling ProjectEX from FTB Sky Odyssey did not solve the issue with the holograms.
Maybe it has something to do with the EMC value they have? Armorstand

Thanks for the detailed report!

I recommend you to spawn armor stands yourself on that modpack, this website can craft you some commands: https://haselkern.com/Minecraft-ArmorStand/

The plugin basically does the same as this command:

/summon armor_stand ~ ~ ~ {Invisible:1b,NoGravity:1b,Marker:1b,CustomName:"TEST",CustomNameVisible:1b}

Try and spawn just a plain old armostand with no NBT, then gradually tick the checkboxes and see when it breaks and isolate that. If they fall down with just the modpack on the server (no sponge, no holograms), then it definitively is caused by the modpack.

I just briefly looked at the changelog, but man, 3.0.37 to 3.0.38 is not a small fix as it seems. 20+ mods have been updated and I guess the guys from Ozone know better what might cause this.

But first try to isolate that issue with vanilla minecraft commands.

[NLBlacky]

Made a vanilla server (No Sponge, just the basic modpack) and all created armor stands fall through the world.

Made an issue ticket in the Github of Project Ozone 3 and FTB Sky Odyssey.

[codeHusky]

I'll drop in and note HuskyCrates is experiencing a similar issue with its holograms. It seems to be some kind of Sponge-Modpack conflict to me.

[NLBlacky]

I can confirm that it is not Sponge. I made a clean server without plugins on it running Sky Odyssey and the issue was still present.

[HeberonYT]

Apparently there is another problem included in this modpack, and maybe it is the same mod that modifies the gravity.
On my Project Ozone 3 server I have used the Spectator mode, all the blocks become visible, but I can not go through walls or blocks, it seems as if I am in creative, but with x-ray. I will be dismantling the modpack to identify which mod causes these annoying problems.

[Cazadorsniper]

@HeberonYT Try looking at Avaritia and Overloaded first.

Hey, this is happening on the new DireWolf 20 update to version 2.5.0

I think it might have to be due to a new forge update, or something of that sort. If there's any more testing that needs to be done, I am open to it. Let me know.

[randombyte-developer]

You should report that to the mods devs. Can you confirm that it works without the mod but still with only Forge?

[runescapejon]

I did some testing and it seem if anyone who has BloodMagic-1.12.2-2.4.0-102 will make hologram/armor_stands fall
