mapclick lag which seems to affect the areas u visit for the 1st time even tho u have the map explored
theres also a visual bug when going up/down stairs - somtimes it looks like u went south instead of north and vice versa (lasts maybe 0.2s then u are in correct place)
sometimes when u stand in place and manas yourself, you will spill the manas on the floor below you (happens maybe once in 200 manas for me, not sure if its a bug or my fault somehow - idk)
theeres also the 2second "lag" which is just a server save maybe make it less often like one each hour, maybe add a message to it "Server is saving" in red so that cunts dont tyhinnk the server is broken and this is just a standard save.
none of these are gamebreaking, just a slight annoyance, idk what these ppl are complaining about, maybe tey're still using windows xp 32bit without directx downloaded on their pc?
