### Tessellate compatibility report
Tessellate fell back to serial execution while running `region-ticking`.
- Suspected mod: `unknown` `unknown`
- Reason code: `unloaded_chunk`
- Suspected frame: `unknown`
- Affected entity type: `unknown`
- Affected block entity type: `unknown`
- Event ID: `69690195-600b-40d2-bae4-8c15234be891`
Reason: falling back to serial region ticking for this session: a region worker needed chunk [1280064, 1280064] at status minecraft:full, which was not loaded. Fetching it would have required the main thread.
### Compatibility guidance
Prefer moving only the unsafe operation: use `TessellateApi.executeOnRegion(level, pos, work)` for world access owned by another region, or `TessellateApi.executeOnMainThread(work)` for main-thread-only state. If the whole type is unsafe, register only the affected type during mod initialization with `TessellateApi.registerMainThreadEntity(type)` or `TessellateApi.registerMainThreadBlockEntity(type)`.
