Start In Spring

This mod forces a new savegame to start in spring March instead of late summer.
On first load of a new career, all fields are reset to a cultivated state to ensure a clean and consistent spring start.

Main Features
- Game always starts in March spring
- Crop calendar is synchronized with spring start
- All fields owned and unowned are reset to cultivated on new save
- Harvest-ready and growing crops are removed at game start
- One-time execution per savegame safe to disable later
- Works on GIANTS base maps

Important Notes
- Field reset is performed with a delayed system-safe method to avoid base map overrides
- On some systems, the info message may appear a short moment after loading
- After the first successful run and save, the mod does nothing anymore
- The game may freeze for a while, while the fields are being reset
