(Copy of my comment on the mod because I didn't think to make a discussion)

Sometimes smoke generates after blocks break even though there is no fire. If you put the delay after click to 10 seconds this fixes it for the most part, but when objects are falling blocks may break more than 10 seconds after you click which still generates the smoke effect. Maybe make a rule to check that the object is actually on fire before generating smoke instead of just detecting if the object is broken outside of the post-click window.

Also the delay after click starts when M1/2 (mouse 1 / mouse 2) is pressed and not when M1/2 is released, so if I'm holding something and smashing it into another thing (lets say the delay after click is set to 10 seconds like I have it) then smoke (without fire generating it) will be generated for every broken block after 10 seconds of me beginning to break stuff. A solution to this problem would be to make it so that no smoke is generated while holding M1/2, and then the timer starts on release of M1/2
