This mod edits the files in Arcology Project decision to allow features not to be destroyed upon construction. This is a quick edit, and i intend on making this mod into a better version.
This mod is an edit of the Arcology project decision and the restore relic world decision, it allows you to keep rare deposits and features after construction is complete. It adds an event to the decision, "efp.1", this stops rare deposits from being cleared. Overwrites Vanilla file, potentially causing some compat issues. There is a dedicated discussion to this.
Note - limitation currently being, it removes some unique deposits like the Earth deposits. Working on a fix.
Road map -
1. Fix Earth deposits and resource deposits, may need overwrite.
2.. Make compatible with other mods that edit Arcology Project ( PD Arcologies, ECS etc)
3. Potential to expand this mod to "Update" features from previous events/ anomalies and make some cool new flavour.
Feel free to report any features missing, or any reports in the discussion area. Also feel free to put suggestions in the discussions.
