Bug happening in Hidden Grotto only

Hi, i figured out there is a weird bug happening only in hidden grotto map while breach is on the map.

it happened multiple times to different people so it's not tied to me.

only happens when you are doing the breach itself, the latency starts to go crazy high like 5k+ and you are forced to log out of the game.

every time this happens map is lost and all the loot u had from the map is lost.

i don't have that much more information in that regard, but feel free to ask more about it.

Thanks.

Edit : that only happens after opening breach
