No experience gains

My low level creatures no longer gain experience.

And the high level ones are gaining too much EXP

The same thing is happening to me as well. My creatures are 37-39, and fighting in realm 30 (level 47 creatures) and not gaining any experience. The character still gains experience, but not the monsters. I used a sigil to check, and it still happens from battles with sigils as well.

Same issue. Two level one creatures not gaining any exp. Changed realm levels (1, 5, 10, etc.), artifact equipped, spell gems equipped, etc but still no exp gain.

yeah affecting me too. Going to lower level areas seems to make some of mine gain exp though

This bug seems to have been addressed with the latest update.
