I created a new save with the Streams mod and every time when I restart my server it does this:

[00:23:08] [Server thread/WARN] [FML]: The following Farseek mod(s) can cause issues with existing worlds:

Streams: Can cause unexpected behavior such as incomplete rivers.

It is recommended to make backups of your world before proceeding.

Continue?

Run the command /fml confirm or or /fml cancel to proceed.
Alternatively start the server with -Dfml.queryResult=confirm or -Dfml.queryResult=cancel to preselect the answer.

Streams version: 0.4.1
Farseek version: 2.2.2
Forge version: 14.23.1.2561
SpongeForge version: 2555-7.0.0-BETA-2764
Minecraft version: 1.12.2

Oops, this was supposed to be fixed as per the Farseek 1.12-2.2 changelog. Seems like I hadn't actually ported the change from 1.11. Will fix in the next Farseek release shortly after Christmas. Happy holidays!

Was this fixed already no hurry just asking

This is now fixed in Farseek 1.12-2.2.3.

I believe this is still occurring on servers with Farseek 1.12-2.2.3 and Steams 0.4.2 @delvr

Thanks armuell, I'll take a look.

@armuell, I just verified and 2.2.3 is working for me - could you post your server log? Thanks.

Sadly I don't have access to the server files. I was reporting on behalf of @unstablecraft as they run the server and they will hopefully upload them soon. Sadly I expect the logs to look very similar to the OP minus some version number changes.

Holy s**t, I forgot about this issue after I updated your mod... Yes it has been working all the time after the fix you released! Closing this now..
