Vista viewfinder pitch snaps upward when any Sable sub-level is within simulation distance

[kosetalhabora-afk]

Description

Minecraft 1.21.1, NeoForge 21.1.250
Sable 2.0.5, Create Aeronautics 1.3.2, Moonlight 3.6.5
Vista tested: 5.5.6, 5.4.4, 4.3.0 (same result on all)

Problem:
When a Sable sub-level exists within my simulation distance, a Vista
viewfinder's aim keeps snapping upward on its own every few seconds.
I can re-aim it, but it jumps up again. It does NOT happen when no
sub-level is within simulation distance.

Already ruled out (removing each did not change anything):

• Aeronautics Camera Sync
• Sound Physics Aeronautics
• Vista Camcorders
• Iris

Possibly related log warning (present on Vista 5.4.4 and 5.5.6):
@mixin target net.mehvahdjukaar.vista.common.view_finder.ViewFinderAccess$Block
was not found sable.mixins.json:compatibility.vista.ViewFinderAccessMixin

In Vista 5.4.4 the class ViewFinderAccess does not exist (replaced by
ReferenceFrame / WorldReferenceFrame / EntityReferenceFrame), so Sable's
Vista compat mixin never applies.

latest.log attached.

I couldn't figure out what to post here; I tried, but it didn't work. Sorry about that.

ive actually experienced this myself. it seems that its perfectly functional except the new data isnt sent to the server so it just doesnt actually update. You can use the debug stick to change it and that works.
