Hi - after update to newest version (Serverversion 1.19.2) its not possible set a number like 0.01 (Zombiekill)
Plugin give me no infos that i earn some money and my eco ist the same. If i set the value to 1.00 it works.
Other infos (infomessage i kill a Zombie works fine)
This problem comes to all mobs with a value 0.(number)

Try enabling /MH debug and check the output in the console (And let me see it, if you need help to read the output)

And check if reward_rounding is set correct in CustomitemsLib/config.yml

Should be "reward_rounding: 0.01" in your case.
