Later:I've downloaded the new script and I've found out some problems with the scripting of every diesel locomotive included in TC3 and and so far a wagon.
I've worked out most of the bugs but there's still one bug that's really confusing.
On the left is a cov van included in TC3. On the right it's a class 08 from eldavo.
Both locomotives from eldavo.
Now this is what confuses me. On the left is an FGA wagon from TC3 and on the right is a class 58 from eldavo.
