Was playing the game and now a setting seems to have changed as on startup I get 'add on 'a3_map_tanoabuka' requires addon 'a3_data_f_exp' then I click OK and it loads to black screen and crashes out stating 'bad version 71 in p3d file 'a3/vegetation_f_exp/clutter/grass/c_grassbunch_hi.p3d' and does not load at all.
This is on Mac OS via steam
Have tried removing local files and reinstalling to no avail
