Elytra predict terrain struggles past 12,550,700 nether

## Some information
Operating system: Windows 11 Pro 25H2
Java version: openjdk 21.0.9 2025-10-21 LTS
Minecraft version: 1.21.8
Baritone version: 1.15.0 (baritone-standalone-fabric-1.15.0)
Other mods (if used): Fabric API, Xaero's Minimap, Xaero's Worldmap & XaeroZoomout

## How to reproduce
Create a creative preferably peaceful single player world.
Get elytra & rockets.
Run "/execute in minecraft:the_nether run teleport 12550000 64 12550000".
Use /seed to get the seed, set the value as #elytraNetherSeed (or set a manual seed during creation and use that)
Set "elytraPredictTerrain" and "elytraTermsAccepted" to true
Run "#goal 30000000 30000000"
Run "#elytra" and jump, fly for a bit till you come up against or past 12,550,700

Also photo attached at the bottom showing how its gliding along this point

However, a bigger issue reveals itself if you are within the 12,550,700 range on one axis and outside of this range on the other axis with same modified settings
Run "/execute in minecraft:the_nether run teleport 15000000 64 0".
Run "#goal 15000000 15000000"
Run "#elytra" and jump

In this scenario, baritone will constantly fail to recompute segment then safely land
