My response:
Mod issue.
This line:
Puts a list into
com.sindarin.farsightedmobs.Config$Server.mobAttributeMap, that cannot be changed. (https://docs.oracle.com/javase/8/docs/api/java/util/Collections.html#singletonList-T-)This line however is not correct:
because it tries to change the list, that cannot be changed.
Sorry for the late reply. I see the problem indeed; I naively assumed that Collections.singletonList would simply create a "normal" list containing the one element, but as you point out, it actually creates an immutable list. Since the mod currently only includes one attribute, this was not a problem. Seems like a simple enough fix, though.
