Might be a QoL, not sure, but I encountered a grave everywhere I died. I prayed at one in Mithra and then alter found two more elsewhere in Mithra (so three in total in Mithra). Map shows two.

It would seem that when mobs get clipped by enviorenemnt they tend to go out of view for melee (possibly also ranged).

This tend to happen now and then with eg. nameds cause they are so big. I've seen it in both mid and alb dunnies.

This might be intended, I only played older versions of DAoC. But when you switch to a weap with con/hits on it you don't lose health.

As is visible on the screendump, the Waylaying Bandit chased me half of Camelot Hills (from map point marked '1' to map point marked '2').

I am unaware of the same issue arises cross mobs, but could be you should look into how aggro resetting is working

fg in Mularn pulled a Hill Person and a Vein Spider, A Wood Eater Worker and a Young Grendelworm baffed. None of these mobs are supposed to be connected for baf'ing

I am not 100% sure but I feel like I remember that I should be informed when a dot effect expires , which I am not.

I believe this spell was supposed to be a bleed but the text says it's a dex/qui buff
