Dynamite does not work properly when duplicated.

If I shoot a copy, I get an error message istead of explosion:


But a non-copy dynamite (spawned by creator or from spawnmenu) still can cause a copy to explode.
Sometimes, when I copied constructions including dynamite, GMod crashed... I don't know in what exact cases it crashes.
It is said, that any issues with this addon most likely are conflicts with something else, but disabling all my addons except of the Nuke Pack didn't work.

Has anyone ever encountered this problem and is there a solution? I am begging for your help.

There might be some grammar, punctuation, and other mistakes in this text, because, in fact, I don't speak english.
