v0.1.5: No-Clip Sync Fixes and Better Litematica Compatibility

Axion v0.1.5 is a small compatibility and reliability update.

This patch focuses on two specific pain points:

• improving no-clip behavior on Paper servers so movement stays properly synced while phasing through blocks
• fixing a Paper regression where fall damage could get suppressed for players globally
• making Axion play more nicely with Litematica's configured tool item when using Alt + Scroll

Highlights

• fixed a Paper no-clip desync where chunk loading could stall while phasing
• fixed a related Paper issue where reconnecting could snap you back to an older server position
• fixed a Paper no-clip regression that could disable fall damage for players who were not even using Axion
• improved Alt + Scroll compatibility with Litematica by respecting its configured tool item

Paper No-Clip Improvements

On some Paper servers, using no-clip to phase through blocks could leave the client and server out of sync.

That could show up as:

• chunks eventually stopping loading around you
• the server silently falling behind your client position
• rejoining and getting snapped back to where the desync began

v0.1.5 improves the Paper-side no-clip path so movement stays much more server-synced while phasing.

In practice, no-clip on Paper should now behave more like you expect:

• chunk streaming continues more reliably while moving through blocks
• the server keeps a better authoritative position for you instead of quietly drifting behind
• disconnecting and rejoining should no longer throw you back to the first place the desync started

This update also fixes a related server-side regression in the same no-clip service path:

• fall-damage state is no longer touched for every online player
• only players actually using Axion no-clip get the no-clip fall-state handling
• normal players on the server should take fall damage normally again

Litematica Tool Scroll Compatibility

This release also improves compatibility with Litematica.

Axion will now back off from Alt + Scroll when you are holding Litematica's configured tool item, instead of only working around the default stick case. That means if you have changed the Litematica tool in its config, Axion should still leave that scroll behavior alone.

This keeps the future Axion hotbar-side Alt + Scroll workflow open while avoiding a common conflict for players who use both mods together.

Server / Paper Notes

If you use Axion on a server, update both the Fabric client mod and the Paper plugin together for this release.

v0.1.5 includes a Paper no-clip behavior fix, so running matching client and server builds is the safest way to get the expected result.
