This is a field effect, which could still be ingame as some sort effect (or a potential effect to be used for modders) somebody should check the code, and see if it is still in the code, and if it is still in the code, see if it is used still somewhere. --Soyweiser (talk) 13:40, 29 July 2018 (MDT)
- field.cpp line 240 has this field defined. In mapgen.cpp the field is generated around artifact anomaly line 7830 void map::create_anomaly function. Line 1418: 'case fd_push_items' describes what the field does. --Soyweiser (talk) 08:29, 2 August 2018 (MDT)
