For whose who downloaded an old version please delete crystal_mission_1.bsp, crystal_mission_2.bsp, crystal_mission_3.bsp and crystal_mission_4.bsp
Delete cross_paths.wad, halflife_hd.wad and jpsecurity.wad too. Then download the new zip file and repace all the files with the new version
Dang, the mapping is insanely good.
Thanks I hope you will test it :)
