Log files are in the userfolder. Just grab the ones shown in this guide and attach them to your reply.
Here, I got the bug again and close the game, the bug started to happen after I created the Jbeam file, the one that you need to create the first time that you use the dealership manager UI. I hope that this is the log file that you need
Ok I think the issues are fixed. So first of all that log file only has an error that relates to the "1963 Volkswagen Bug" mod, caused by weird jbeam file structure in the mod zip. All vanilla cars have the jbeam files in the vehicle folder but this one has them in subfolders. So I've added code to handle such vehicle file structures without causing errors. Second as for the "satsuma" mod you mentioned, the issue with this one was the name of the vehicle folder didn't match the model name of the car. The model is just "satsuma" but the folder is called "satsuma_100" so code that uses the model name to find the vehicle folder fails. Once again all vanilla cars use the model name for the vehicle folder name so it worked fine with vanilla cars. After adding code that handles this situation the car loaded correctly in the dealership manager app. Thanks for the bug report, although this was caused by mod weirdness the changes I made should improve compatibility with other mods that use similar folder structures and different names for the model vs folder. The fix will be released in next version which should come out soon, possibly this weekend if everything goes well.
