Research direction

Start by reproducing the freeze with an upgraded world from 1.12.2 using Debugify 26.1.2.2 and Fabric Loader 0.19.2. Compare the end of optimization with the missing-chunk behavior when entering the world; done means the optimized world loads without freezing and its chunks are present.
