Is there any possibility to automatically (in a "bash manner") resave/update all maps (from original F2 dat) for changes I made with protos (items, critters). So far I have to open/save each map in editor separately!
However, there is this option in the mapper:
F11: /Rebuild all (Librarian menu - need librarian=1 in cfg)
I have never been good with the mapper, so I am not sure what "all" fully means and I would recommend you make a backup copy of all work before testing this.
It builds the maps from text files the mapper cfg has a line
save_text_maps=0
If it set to 1 it will save text files beside the maps. The rebuild is done according to the data found in the text files. Well at least as I know haven't used it in a while.
It does take a very long time to do this - up to an hour on my shitty machine, the text files are saved in the map folder. So if the computer doesn't react just leave it and come back.
