in some situations BBS can always read wrong hof. for example, the hof file can always be wrong when i want to drive in grand paris moulon. although the hof names are different and i've selected the right one in BBS, BBS seems always to read the first one and in OMSI the hof will be wrong.
sometimes it can be totally wrong. i have selected the right hof (no other files with similar names) but in the game it could be the very first hof in the bus' folder.
and BBS can read and buy AI buses. they are not shown in OMSI but in BBS. it could be wrong when buying new buses, although you can find which is the AI according to the order in the vehicles directory
