📝 Walkthrough

Walkthrough

The map generation dialog adds a Reload Options button. Clicking it resets extraction state and reloads options for the current generator version. The button receives the existing base and hover styles.

Changes

Map generation option reload

Layer / File(s)	Summary
Add and style Reload Options control res/games/mapgen.ui, res/client/client.css	The dialog adds buttonReloadOptions between the reset button and spacer. Existing button and hover styles now apply to it.
Reload dynamic generator options src/games/mapgenoptionsdialog.py	The button connects to reload_cmd_options. The method disables the dialog, resets dynamic options, obtains the current generator path, and reruns extraction. Extraction clears previous results, and update_version avoids duplicate versions.

mapgen_manager.currentVersion is below Version("1.12.0"), before disabling the
dialog or invoking options_extractor; preserve the existing extraction flow for
supported versions.
