You think it is bad, I have been busy sorting out a list of the errors known to date.
On US long card we currently have 4 duplicate numbers....
MB7 is both Runway Wrangler and Tesla Model S.
MB29 is both 2014 Chevy Silverado 1500 and Quarry King.
MB44 is both Sowing Machine and Drill Digger.
MB107 is both Dune Dog and Frost Fighter.
On ROW short card, (at least) 13 models have been released with different numbers to where they are on US long card....
MB25 Rain Maker is MB24 on short card.
MB26 Mountain Mover is MB25 on short card.
MB29 2014 Chevy Silverado 1500 is MB28 on short card.
MB44 Sowing Machine is MB42 on short card.
MB69 International WorkStar Brush Fire Truck is MB74 on short card.
MB74 Blockade Buster is MB70 on short card.
MB87 Snow Ripper is MB85 on short card.
MB88 Chevy K-1500 4x4 is MB112 on short card.
MB98 Terrain Trouncer is MB93 on short card.
MB101 Land Rover Defender 110 is MB96 on short card.
MB102 Jeep Wrangler Superlift is MB97 on short card.
MB107 Dune Dog is MB99 on short card.
MB113 Ford Bronco 4x4 is MB103 on short card.
You may note that some of these are one from each of the pairs (apart from MB7) of duplicated US numbers, so it could be that the ROW range is sporting correct numbers. But this means that most of the early US batches this year are wrong. THis could be a huge mess up with Mattel and US long card numbers.
