You're quite welcome. Seems to work now. I'm not getting any errors at least. Thanks for the choo-choos

Thanks for providing the error report. When publishing an asset, the name prefix changes from file name to the newly assigned steam ID. And I simply forgot to update the effect definitions accordingly.

Just updated all definitions, it should work now. Before testing, please unsubscribe and resubscribe to make sure steam really downloads the updated assets.

No, I have both enabled.

You probably subscribed to Extra Vehicle Effects but not to Vehicle Effects, then you get a info message about a missing dependency.
