Flashback Neoforge Fixed Mod patches compatibility issues for Flashback on NeoForge 1.21.1 through Sinytra Connector. It preserves modded packets and keeps replay snapshot states intact during recordings. The mod adds working compatibility for moving parts from Create, custom sub-levels in Create: Aeronautics, and distant terrain in Voxy. With this fix in place, you can record complex modded machinery without broken replay files.
