But you have good eyes, I didn't even notice!
The problem is relatively easy to fix!
Open the "hungary_def.scs" file (eg. with Total Commander), go to the "def/vehicle" folder and delete the "traffic_storage_truck.sii" file.
If someone else has a problem with this, do the same!
Thanks for reporting this error and sorry I didn't notice!
P-S.
I fixed the bug and updated the upload!
It can be downloaded from the same link!
