Has anyone encountered this situation?
When you shoot a fuel barrel, it simply disappears, and nothing happens—no big fire, not even the crisp sound of being hit—as if it never existed.

I don't know why, and I can't replicate this issue.

I just placed the fuel barrel in the direction where the horde might appear, as usual, and hoped that the blaze would kill the infected.

Usually is a plugin causing that, try removing them all and try again.
