Due to the activity of the other artists in creating new road vehicles graphics, I need to review the IDs usage schema. That means I need to make a new version of the Long vehicles. Because changing the version is a difficult process, that makes a lot of problems to the set users, I'll do it step-by-step. I'll also try to keep as much IDs untouched as possible. The changed files will have interim version 3 ¾, until all the files will have that version. Then the version will be switched to 4. With the version 3 ¾ the GRFIDs will stay unchanged. To prevent the confusion, the file names will be changed. Instead of prefix "3" they will have prefix "334".
For now, as the first step of the process, the Spitzer trucks and McTrucks become version 3 ¾. For the Spitzer trucks users it will mean, that they have to update all the Spitzer livestock carriers, because they have different ID now. For the McTrucks users it will mean, that they have to update all the McTrucks, because their IDs are supposed to be bus IDs now.
Sorry for inconvenience, but I hope new buses is the enough reason for it.
