Curious if my memory is wrong, or if the level of some mobs are wrong? Nothing crazy, but for instance I always leveled 10-18/19 in the plains on grove nymphs, which had specific camps that were level 10, 12, 15, and 18 whereas now they seem to be a semi random mix.

Anyone else notice stuff like this? Also, how might I contribute to fixing such issues?

A minor complaint in the grand scheme of things - excellent job on the server!

I remember grove nymphs the same way, they used to spawn in camps of the same con (+/- 1 level maybe). But GMs need evidence to make these kinds of changes, which levels should spawn in which grove, etc., they dont rely on player's memory alone. If you have any sources you can open an issue in the tracker. https://www2.uthgard.net/tracker/

One could also compare with the live server, if the plains is still a 10-20 zone, but I dont have an active account.
