For YUP 9.0 and potentially earlier releases. (http://www.nexusmods.com/newvegas/mods/51664/):

Update VendorBulkBuyFixerSCRIPT (0600321F) to match the amount of the casings that they are supposed to give.

Per script description update:
; Diskmaster - Corrected Case Box amounts per box (200 -> 25) and ECP Bulk Box amount (200 -> 100). 06-05-14
http://www.nexusmods.com/newvegas/mods/39981/ (CaliberX) and YUP compatiblity patch. (4.017 and 9.0 as of commit timestamp, though the mod really only affects CaliberX and should be paired with the one in the YUP folder in this repo for full effect.) Due to how old the original mod is, four identical to master script records exist that was originally for the 1.2 bugfix as noted in one of my posts for the ammo mod. This merely forces the script to apply properly to the offending records and can be obsoleted when removed from CaliberX's current release.
FormIDs 166d45, 166d46, 166d49, 166d4b
Update Readme.md
Initial version of CaliberX 1.4 patchup project.

Changes so far:
Ammo40mmGrenade (7ea26) Value 5 -> 12, Added QNAM - Abbrev. 40mmG (YUP should not change Short Name and instead add Abbrev instead here)
