i like to play quake in DP without any kinda addons sometimes too, and it always bothered me that in standard quake the position of nails coming from the nailgun seems to be off.
thanx to seven's great help ive managed to apply the nails position fix he made to both mission-packs as well

REGULAR QUAKE

HYPNOTIC (MP1)

ROGUE (MP2)

nail-position fix for regular quake -by seven

nail-position fix for both mission-packs

ROGUE nail-position fix +misc fixes for DARKPLACES

the updated fix for missionpack2 AKA rogue includes fixes for the elevator in R1M7 and includes fix for the plasma-gun not firing as well,
and now also includes fix for broken buzzsaws in DP builds from 2014 and newer, which are all done by seven! thanx for those couple fixes seven

these progs.dat are engine-independant, and as such will work with ANY engine!
