High Latency in Maps

Hi,

From yesterday i am facing an issue in the game, where i get ~70 ping (SG server, im located in India) when in campaign. However, in maps, if im idle i get ~70 ping but as soon as an enemy appears i am stuck in place and the ping keeps rising, if the enemy dies, then the ping goes down to 70 again. but if i take a few steps forward, and there is a new enemy the ping shots up.

I am unable to play in maps (campaign is not a problem at all)
