@Forces Believe it or not I know a bit of what I am talking about.
The OP had reported two bugs.
The second one (being able to pack with less logs than required) is actually a game bug from SpinTires that never got fixed.
The first one (missing logs on drop load) is an issue that is caused by some mods (and not only truck mods, also maps can cause this). But it will happen on any map, with any truck (even the stock trucks), as long as you are subscribed to the broken mod! And that's the annoying thing, because you have to find the one mod that's causing this. You could unsubscribe from all of them and add them back one by one, or you could unsubscribe until it's fixed. But the more mods you have, the more painful this gets. I have been through this. That's when I started to dig through the log file, until I realized I could identify the broken mod from this. I never wanted to fix any mods, I just wanted to give the OP a way to identify which mod could cause this, so he could remove it. Obviously @Unster got lucky and removed the mod before even trying my method, but I am pretty sure it would have worked.
Again, you only need to be subscribed to the mod, you don't even have to use any vehicles or add-ons from it for the bug to occur! I agree, that these mods should be fixed and I tried to contact the authors of these mods, but they either say that nothing is wrong, or they just don't respond at all.
Also I just used zidons Landrover mod to play around a bit.
That mod has a "classes\models\pjt7q3op.xml" that's causing problems.
As long as you are subscribed to this mod, any short log truck (even the stock trucks) will miss some logs if you drop your load and you will get these errors:
Mesh| Cant load mesh 'meshes/models/pjt7q3op' - XML 'meshes/models/pjt7q3op.xml' not found.
Terrain| Cant load Models Brand pjt7q3op
These are the facts:
- The time stamps of the error lines in the log file exactly match the time when I clicked on drop load ingame.
- The number of error lines in the log file matches the number of missing logs.
- Deleting the file mentioned in the log from classes\models\pjt7q3op.xml fixes the issue with disappearing logs. (And I haven't seen any problems with the mod itself after that).
- Adding a mesh as _m\models_pjt7q3op.xml will spawn that item instead of the short log. I copied one of the spare tires in its place to see what would happen, and I got 3 logs and a tire, when i dropped the load.
