WorldAcceleratorFix

by WinExp

WorldAcceleratorFix, a Forge mod by WinExp, repairs a GregTech accelerator fault where the machine stops working after a rejoin or reload.

ForgeServer-side onlyGNU Lesser General Public License v3.0 onlyOpen source1.19.2 – 1.21.8

What it does

The fix targets a problem in GregTech's accelerator machine that stops it working after a game reload. Once a player rejoins or reloads the world, the machine can stay idle until the affected chunk is reloaded; this mod corrects that behavior. It runs on the server alone, so players connecting to the server need nothing installed. The fix requires GregTech CEu Modern and is published for Forge across 19 release versions, 1.19.2 – 1.21.8, under the GNU Lesser General Public License v3.0 only, and the source code is open source.

Key features

  1. Accelerator restart fix

    Keeps the accelerator machine running after a rejoin or reload instead of stopping.

  2. Chunk reload handling

    Corrects the affected chunk state so the machine resumes without manual intervention.

  3. Server-side operation

    Only the server runs the fix, so connecting players do not have to install anything.

Questions

Does WorldAcceleratorFix need GregTech CEu Modern?

Yes. GregTech CEu Modern is a required dependency and must be installed on the server alongside this mod.

Is the problem fixed in newer GregTech builds?

The author reports that the fault was already resolved in a later GregTech build, so a server on that build may not need this mod.
