Config file format changed slightly. Delete your old config file

... oh and old Infernal Mobs savefiles (old worlds with it) are not compatible, sorry

Well I shouldn't have an old savefile of Infernal Mobs and world anymore cause I should have made a new world after experiencing issues with Infernal Mobs 1.17.1.

Btw I remember when I tried Infernal Mobs for 1.14.4 and it didn't work which I wonder what was causing that issue to begin with since you've fixed that problem already.

Anyways if I do have an old Infernal Mobs config/savefile then I'll delete it so that I can try Infernal Mobs 1.17.1 again when forge reaches stable since 37.0.34 literally "killed" 15 out of my 33 1.17 mods that I was playing with before that forge update which is/was mildly infuriating and disappointing..
