[Minor Update] Easier road construction and Flatten operation. — Reshaping Mars Steam update #554309

Greetings! The main contents of the update include: New Operation Roads can be built automatically from head to tail, no need to click one by one. The Flatten operation can be set to "fill only" or "extract only" by clicking the "..." button above. Game Improvement The work unit no longer overrides its own charging task when there is dual highest priority. Fixed an issue that may cause the game to freeze in some cases. Thanks for your support, Wish you good game and have fun~
