first, it is about the partner system,whenever i want to give my partner some gift, it is suddenly lag like hell (if i want my partner have 4 gift, have to click 7,8 time to give her the gift) and after few minutes, it is back to normal and the rest partner can get the gift normally (no lag anymore)..and the next time, thing repeat.....lag and lag
second. when i am going to room of rites, it is lag like hell, and when i make some damage on the enemy, it take 3,4 s to them to get the damage...and they are teleporting too..
wondered if i am the only one? anyone got the same problem like me?

Yeah I think it's latency/processing on your side because that rarely happens to me when it actually does happen.
