i think it happened when i went to go do that mission in gomorrah cause i heard most people lose companion inventories when they enter casinos.... is there a way for me to get boons inventory back? could someone please explain?
WOW! GODAMIT! i checked rexs inventory and hes also missing everything too!!
WTF? WHY DO THEY HAV A PATCH THAT MAKES SHI WORSE? I KNOW THEY DIDNT MEAN FOR THIS TO HAPPEN BUT DAM THIS IS BS!!

edit: well, after reading the patch notes thru, i saw this 3/4 the way down "Fixed Gomorrah holdout scripting to properly affect companions."
APARRENTLY NOT! how the heck did this get fixed if the exact opposite happened 2 me? MAKES NO SENCE! GRRR!

UPDATE: I FIXED IT! SO IF ANYONE ELSE HAS THIS PROBLEM THI IS WHAT I DID TO FIX IT
first i deleted my 1.06 game patch in the "game data utility" folder.
then i started the game and installed the game data BUT i DIDNT install the 1.06 update. instead, when it asked me if i wanted to install 1.06, i clicked cancel so that it would stay @ 1.0 and then i loaded my save file. once i was on the strip, i entered gomorrah, then exited gomorrah, then i checked my companions inventories and all my weapons etc. were back!

then after that, i deleted my DLC and reinstated it (NOT NECESSARY BECAUS THE GAME CAN STILL READ YOUR INSTALLED DLC EVEN ON VER 1.0)
finally, i reinstated the 1.06 update and its working gr8!
hope this helps!

UPDATE 2: it happened again.... everything lost.. now i hav 2 do this again......
