I found this bug a loong time ago.. And made post about it in the forum. No-one cares about my inventions anyways, left besiege because of this.
And even an...
+ 2 speed Gearbox
+ Sturdier chassis
+ Differentials (Front diff, central diff, rear diff)
+ Faster turning
+ Shorter rear&front axles
+ An engine (V1 features a wheel as an engine, V2 a dedicated engine)
- Heavy and laggy.
Another suggestion, but i don't know if that is possible, to add a function to change the settings of the selected blocks (avaiable only if the selected blocks are all the same)
Anyways, take your time Tesseract, this is just a suggestion, take them as inspiration if you want to do something.
