Unfinishable Itherian realm quest

Windows 10, Siralim v0.1.12: I’m in an Itherian realm, with the quest “Generic Fetch Quest: Find Tiny Coins in this Realm by defeating enemy creatures.”

I’ve defeated all creatures in the realm, and am at 3/5 coins. Realm effects are

[R] Contains extra nemesis creatures (<- probably the culprit, if nemesis…ies… don’t give out fetch quest targets)
[E] Immune to spells (Gotta love being a sorcery mage :/)
[R] Inhabited by crusader race

I think you’re right - it’s probably the Nemeses that are causing the problem. Thanks for the information!
