v1.12-0.4.9

• Fixed stone "bridges" appearing across Streams.
• Added an option to restore the legacy Streams generation from Streams 0.4.7. Enabling legacy generation reverts a change
  in Streams 0.4.8 that prevented infinite recursion crash in some modpacks,
  but also caused Streams to become too rare or too small.
  If you're starting a new world and not using a modpack affected by the crash, you can enable this option by either
  adding -Dstreams.legacyGeneration=true to your server's Java command or launcher installation's JVM arguments,
  or setting environment variable STREAM_LEGACY_GENERATION=true.
  Once enabled for a new world, that world keeps the same value even if the global setting changes later.

Built using Forge 14.21.1.2443 and MCP mappings stable_39.
