In game Mana Regen

[amxdark]

On the server I am currently playing one some of us are having an issue where using #mystats shows the base mana regen, the correct item total, the correct spell total, but the total number is lower and i am actually physically getting the lower total number that mystats shows. The issue is somewhere along the lines its counting the mana regen but then not actually adding it to the total. I am clearly not hitting any caps with this. Also i can take off/on a 5 mana regen item and only lose/gain 3 mana regen in total and actual seeing the mana per tick. There are people on the server who do not have this issue, and we all are using the same client. I can't figure out whats diffrent that they dont have that problem but some of us are losing nearly half of our mana regen. Does anyone have any insight??
