The cobwebs that follow the projectile are causing the server to have a lag spike whenever they are being placed. I tried to disable these in the config by setting the variable under firing to false but the smoke blocks keep appearing anyways.

I added the missing check if the option was deactivated

I might sound stupid but I don't understand what you mean lol xD can you elaborate on that sentence, sorry.

I fixed it, the option was in the config but it was not used in the program. Therefore, whatever you set in the config had no effect, should be fixed in 2.5.6
