Hey @Lone-Rider!
Trucky app just made an announcement detailing yours or a similar issue in their Discord server which can be found here: https://truckyapp.com/discord .
Here's what their announcement says: "As TruckersMP introduced the economy recalculation and new game time management, there are some rules to apply when using the Dispatcher: - If you plan to play on TMP, don't add jobs from Desktop but use always the Dispatcher in game (ALT+D) - Add jobs always after connected to a TMP server - After reloaded the save, don't let too much time pass or the jobs could expire (i.e. fly to a garage or sleep) (basically if you don't do this, added jobs will disappear) thanks for your attention and happy Dispatching"
Here's the link to that message as well: https://discord.com/channels/393525215918817280/394537237813133322/875778774795448390
Hope this helps!
