They should've released a patch for the most obvious issues and new crashes by now. The trim_n/d/etc errors, AT LEAST.
The thing is that the issue you mentioned is not a problem of the game. It's caused by some older mods. There is nothing we can do about it. You either see if there is an updated version of those mods, or remove them. More info here: https://www.beamng.com/threads/0-8-0-1-discussion-feedback-bugs-reporting-thread-read-1-post.33989/
I'm aware other mods cause it, but mods being able to affect default content in this way is, indeed, a problem with the game.
And even so, using a hundred message boxes that each freeze the application (despite the error referring to a minor visual inconvenience) is the complete wrong way to handle to them. They could be reduced to a simple console message (this is more what my original message was referring to).
There are better ways of doing that, like leaving the shared files (the ones that are used by various mods) protected, and allowing you to upload new files to use instead for a particular vehicle.
The original files are 'protected'. The mod 'overlays' files over the default content usually. Don't use the mod maybe?
The issue is not with using the mods (I'm not even sure which mod(s) causes it). The issue is with the vanilla content giving the error messages.
Those errors are required so that you know something is not working properly. Restraining them to console error will make nobody notice it. It's not vanilla, not after using that mod. The mod in question will make the game create a broken 'materials.cs', stored in Documents/BeamNG.Drive/vehicles Even if you remove the mod, the cache remains. Using the 'Clear Cache' button is required. The problem wouldn't even have appeared if the author didn't do the mistake of making the mod 'overwrite' the original 'materials.cs' file. I believe the author of the 'Mad Mod' thing already fixed it, so just get the newer version of that mod.
I think he is suggesting that when the error occurs, the game should detect what mod is causing the error and disable it automatically. I don't think that is a bad idea, as long as players can turn it off, and it is clear that the mod has been disabled.
Devs, I want to say, you have changed my life. Every time I drive somewhere, I go "Oh look! That one is like a/the *insert BeamNG car here*!" (there is a car in my town that looks JUST like the Ibishu Covet.) Thank you.
So I am new here, tried looking for the Powertrain Visualization app in the mods and everywhere, still couldn't find it. Could anyone help point me in the right direction?
