Serious lag occurred in some dungeons (epic quests).

[Kustale]

Describe the bug

After entering some dungeons and after a certain amount of time, the lag gets worse.

To Reproduce

in Revoldic Dam Underground Base

1. Enter the Revoldic Dam Underground Base map
2. Narin ends the conversation and proceeds to the stage
3. Enemies appear.

in Henesys outpost

1. Enter the Henesys Outpost.
2. Proceeds to the stage.

Expected behavior

As the character climbs up the map, the enemies pile up. The lag gets worse and the client freezes (more often than not completely). The server keeps overflowing the logs.

Stack trace of the error

Not an error, but an infinite loop.
