Yeah it does matter it was fixed and now they forgot to include it in the 10.5's, it's complete complacency.
From twitter..
BC2 long load times back with 10.5? CatalystMaker - was supposed to be there - found out its not.Will get hotfix ready
ETA on BFBC2 loading times hotfix? CatalystMaker - a day or two
It's complacency but it's nothing really major considering you can still enter the server, at least they've realised their mistakes and are addressing the issue asap, unlike Dice.
