I need to have a look at ars noveau to see why they mixin into the chunk sync. Does that mod have anything that allows you to see far away chunks?

[GetSnekt]

i don't actually know anything about that but from my knowledge it does not let you see far away chunks.
EDIT: now that i think about it maybe the item called "enchanter's eye" would do it or maybe the "scry crystal" item.

[Nick1st]

Does it happen with only Ars Noveau? Or only with both

[Camriod]

Having this exact same issue, except Nature's Aura doesn't have to be present at all.
Immersive and Ars just heavily dislike eachother in chunk loading.
I had reported this issue on the for forge repo, since the modrinth page redirected me there
not sure if that info is still useful or not

[Encharrion]

I ran into this issue, without Nature's Aura. I believe the issue is that both Ars Nouveau's ChunkMapMixin.java and Immersive Portals MixinChunkMap_C.java attempt to modify onChunkReadyToSend. The Ars Nouveau mixin appears to allow chunks near a camera to be sent to the player viewing the camera, according to the comments. I'm guessing Ars Nouveau has a scrying spell that wouldn't really function without this. Not knowing anything about mixins, I wonder if both mixins being on the same priority of 1100 might be part of the issue?

[Alexthw46]

Setting Ars mixin priority higher allow to at least load together with most functionalities working.

You should refrain from using Overwrite in Mixins and use Inject or MEx (now included by default in Neo) Wrappers as Redirect to avoid mixin clashing like crazy

[Nick1st]

This mixin is an overwrite, as we want to crash rather than causing a lot of really hard to detect issues that can cause crashes and corruption later on.

[Nick1st]

I'm aware that this is not a great solution, but this needs to be fixed by adding explicit compatibility.
