So for some reason the 250x, 350xf, and the 450xf bikes that PiBoSo made, arn't showing up. They were for a long time but one day when i went into the game they didnt show up in any of the catigories. I still have the files for them in my bikes folder that i used them when it worked but for some reason they just magically wont show up in game, not even in the MX1 or MX2. There is nothing wrong with the files because all of the bikes worked with the files but they just magically disappeared. Does anyone know why?
