This read me is for the replacement Freight sound, but, it will also apply to several other sets as new sounds are updated.

If you are playing a game and You will hear the the wrong sound played (Usually a jet engine). Don't worry, You can fix it Yourself.


**** The cause! ******
Once a sound for a vehicle in LoMo has been modified or changed*, any save game or scenario that contains that vehicle will have the wrong data. The result of the  data being wrong  will result in the game getting confused and playing the first sound it finds. Usually a jet engine.



****How To fix this bug yourself*****

**For scenarios**

For scenarios that were made before object with the new sound was made, Open the scenario in the LoMo Scenario editor. Usually you have to hit the  "up folder icon" to find the scenario. Once You opened the Scenario, you have to go to vehicle selection, Then uncheck and recheck the Vehicle that is  problematic. If you are unsure, it wont hurt to just recheck all items, Once You have done that.  save the scenario. now you can play it with the updated sounds.
*note this is alway a good idea for any scenario that is older that uses the US set as the set is constantly changing.

**For Save games**

For save games that were made with an older version of the  Vehicle, You will need to get the tool called "LocoMod". Start up locomod and open the save game you wish to fix. Go to the "Objdata" tab, Look at the "vehicles" section. Once you are there, scroll down the list looking at all of the checked vehicles. for each checked Vehicle, look in the window on the mid-Right called "Uses". If you see any sounds that are not checked, you need to go add them the the save game in the "sounds" section. 

Once you have updated the missing sounds, Save the save game and load it up on LoMo, Problem fixed! 


*the sound internal ID is changed
