Affected Mod Versions:

• Forge version: 1.10.2-12.18.2.2120
• RTG version: 4.1.1.5
• GeographiCraft version: 0.7.5
• Streams / Farseek version: 0.2.1 / 1.1
• Biomes O' Plenty version: 5.0.0.2091

Issue Description:

I found an apparent square snow pattern on streams in an Ice Mountains biome.

Seed: -4304547433725488807
XYZ: -708 / 120 / -257

Steps to reproduce the issue:

1. Install RTG with GeographiCraft and Streams.
2. Generate a RTG world.
3. Find a snowy biome with a stream in it.

Thanks for the comprehensive report - we'll try to reproduce this in our development environment and see if we can figure out what's going on.

If it makes any difference (for reproducing with given seed), set B:SeparateLandmasses=false in geographicraft.cfg.

That will definitely make a difference, thanks.

Here's the mod list. It's my private modpack which also runs on a dedicated server where I use MSM. No Bukkit etc.

Edit: I reduced the list to the necessary mods, updated to the latest version and can confirm that the pattern is still generating at given coordinates.

• Biomes O' Plenty 5.0.0.2093
• Farseek 1.1
• GeographiCraft 0.7.6
• Realistic Terrain Generation 4.1.1.6
• Streams 0.2.1

Encountered this on 1.7.10 when I had streams before I decided to pull it from my pack. I think it might be an issue with streams itself, rather than RTG.

It could actually be another mod that is interacting badly with the way Streams generates it's streams, which is during the biome decoration process. There have been issues in the past with mods DENYing decoration events which prevents Streams from finishing what it's doing. (MagiaNaturalis in 1.7.10, See #870). However, the nature of these strips doesn't quite fit that, and it's also strange that they are all 8 blocks wide.

@mankra Can we get a full mod list, please. And is this in a dedicated server environment? If Yes, is there a plugin manager in use? (Bukkit/Thermos, etc..)

After looking at those screenshots a bit closer, it reminds me of the issue Streams used to have with the stone bridges that would generate perpendicular to the stream.

B:SeparateLandmasses=false in geographicraft.cfg

@delvr

This is only happening where there are streams, nowhere else.
The strips coincide with chunk borders.
This is likely from a bad iteration in the Streams decorator?

Please note the edit in my modlist post.

I can't reproduce this world. Are you using modified config settings in GeographiCraft?

Thanks for letting me know, I'll take a look on my end.

@delvr Just tested a few snowy seeds with the latest versions of RTG, Streams & Farseek and didn't see this issue at all, so hopefully @mankra can confirm it's working on his side too.

Nice work on the SpongeForge compatibility by the way! 👍

OK this should be fixed in the new Streams 0.3/Farseek 2.0 version. Please give it a try and let me know of any issues, thanks!

Fix confirmed. Thanks a lot! :-)

Ahh. OK, is there a 0.3 for 1.7.10? I did not see it
EDIT: Never mind, this is not the Streams thread, this is an RTG thread.

Streams 0.3?!? When/where was that released?
