Troubleshooting

The add-on does not activate

• Verify Minecraft 1.21.1, compatible NeoForge 21.1.x, Java 21 and the exact dependency versions in Getting Started.
• Install the compatibility add-on alongside both required mods. Dedicated servers and clients need matching JARs.
• Make sure the world type is an UltraTerraForged Overworld.
• Run /utfstreams status as an operator. The preset must enable winding rivers or raised water.

River currents are missing

Ensure vanillaWaterFlow=true and flowVanillaRivers=true in config/streamsreflowing.properties. Currents use Streams Reflowing's grid preparation, so newly visited regions can take time. Existing baked fluid blocks are not replaced.

Water appears to run uphill

The addon skips detected uphill current segments by default. It does not lower, reshape, reconnect or repair the underlying water and terrain. See the configuration and limitations guides.

Report a reproducible issue

Open a bug report with:

• Exact versions of all required mods and the Java/NeoForge runtime.
• World seed, preset and whether the affected chunks are new or existing.
• Coordinates including Y, expected behavior, observed behavior and screenshots.
• Diagnostic command output and relevant configuration values.
• Logs with private server details, user tokens and personal information removed.
