I've been playing for a good many years, mostly solo. I never messed around with homunculus, but before the change They used to gain experience and level up.
I made one and now he is at level 0, with no exp bar and gains no experience. I can see the difference in exp.
For example with out him summoned and I kill a frog, shows that I gained 22 base experience and when I do have him out on the map and I kill a frog, it says I've gained 20 base experience, so there is a percentage difference. The exp is going somewhere, but not to him.
I'm only level 70, but i've been killing enough things that he should have gotten some experience, or at least to level 1. Or i'm missing something. does his low loyalty have anything to do with it?
