There might be a non-working component that's first in the queue. There are several ways of fixing this. i'm just going to tell you the easiest one.
NOTE: you might want to back-up your components folder in case something goes wrong
Step 1:
Go into the components folder and look through the .txts that involve wheels. (you can be sure of this by opening a .txt look for base = [insert component catagory] if base = Wheel (or something like that) then you have a wheel)
Step 2:
Find the one which has the lowest sort number (which is in the .txt so have fun looking through them all
)
Step 3:
Delete the .txt which has the lowest sort number(in the wheels catagory)
OPTIONAL: Delete the folder associated with the .txt in question.
As for random weapons crashing they are probably broken as well as i got the same result.
Hope this Helps
Impossible
