- *  \li \anchor newgrf_changes  (1) in-game changes of newgrfs may reassign/invalidate IDs (will also cause other trouble though).
- *  \li \anchor dynamic_engines (2) engine IDs are reassigned/invalidated on changing 'allow multiple newgrf engine sets' (only allowed as long as no vehicles are built).
