Blocks & Bogies Compatibility Update

We’re happy to announce that compatibility between "Create: Blocks & Bogies" and Railway 1.21.1 has been fully restored! After addressing the issues, the SNR compatibility code that was removed during the 1.21.1 port of Blocks & Bogies has been reinstated. Key mixin issues, caused by changes in NeoForge 1.21.1, have also been fixed to ensure everything runs smoothly.

A new feature has been added, allowing bidirectional menu switching between Blocks & Bogies and Railway bogey menus, making it easier to use both mods together. While Blocks & Bogies remains fully functional as a standalone mod, it now works seamlessly with Railway 1.21.1. When you play, ensure you are using the latest version of Blocks & Bogies, so that the changes from the Blocks & Bogies PR #31 work properly.

Thank you to everyone who has reported new issues and helped with the debugging process!

Other Information

After extensive testing, we've found that Blocks & Bogies is currently incompatible with Steam 'N' Rails Neoforge. While compatibility might improve in later updates, for now, B&B is being marked as incompatible. That said, you can still use B&B at your own risk, and during testing, we have reported success with no issues, but others have been experiencing various problems. If you encounter problems and B&B is in your mod list, try testing in a fresh world without it to confirm whether it's the cause. If you're able to get both mods working together, great! Just be aware that some train and bogey features may break unexpectedly.
