Additional context

I messed around with 40x46mm.json and found that calling an effect in the abstract works but any effects called with extend eg.( "extend": { "effects": [ "EXPLOSIVE_m433" ] } ) won't activate. This is also why gas grenades are the only ones that work as they work through "drop" and not "extend".

Yes, extend does not work too well with item definitions as they are not using generic factory.
