The 6.0 update has added many things, to avoid errors please replaced all files if you have already got the mod installed, if you want to keep your current Comapnion, copy your Data.ini somewhere else then copy all files from the zip, and replace the new data.ini with your old one, or copy CustomAnimations.ini from the download zip (in DownloadZip\scripts\Player Companion\) into your Player Companion folder as well copy UnionDepositoryGetawayCar.ini (in DownloadZip\scripts\Player Companion\Heists\) into your scripts\Player Companion\Heists\ folder, as well as make sure to replace HKHModHelperNew as you will get a crash in the Union Depository Heist if you dont!
