Sinytra Replay Fix
Fixes Replay Mod showing wrong items, blocks and entities when you play back a recording made in single-player on a modded Forge 1.20.1 game. Servers already worked; this makes single-player recordings behave the same way.

About this project
What does Sinytra Replay Fix add?

Record something in single-player on a modded Forge 1.20.1 game, then watch the replay: modded blocks, items and entities can show up as other things (a block turns into a mob, a held tool turns into a plain block), and the log shows errors such as Expected item to be instance of ... or Invalid entity data item type. The same mods recorded on a Forge server play back fine.

SRF is an unofficial add-on. It is not affiliated with or endorsed by Sinytra or Replay Mod. Built and tested with Replay Mod 2.6.15 running through Sinytra Connector on Minecraft 1.20.1 Forge.
- Only new single-player recordings made with SRF installed are fixed. Recordings made before cannot be repaired.
- Server recordings are left exactly as they are (they never had the problem).
- Tested only with Replay Mod 2.6.15 through Sinytra Connector. SRF hooks into Replay Mod's internal code, so other versions may not work.

- Replay Mod by the ReplayMod team (CrushedPixel, johni0702 and contributors), licensed GPL-3.0. SRF hooks into its recording code.
- Sinytra Connector by Sinytra, which runs Fabric mods on Forge.
