Mods included:
Quark-r1.6-179 (last version for 1.12.2)
AutoRegLib-1.3-32 (last version for 1.12.2)
MIA 1.12.2-0.2.2a (last version)

For some reason with the MIA mod present, frogs and crabs from Quark have their items drops always smelted (no matter the mob is on fire or not)

the solution i found was disabling the "Add cooked mob drops" config
