A Warzone bug affecting the Heartbeat Sensor appears to be causing short freezes and connection losses.

Warzone subreddit user u/Leeuwarden-HF posted footage of the bug in action Thursday. In the video, Leeuwarden-HF's game runs normally until they attempt to take out their Heartbeat Sensor. As soon as they do, the game freezes completely for around four seconds before stuttering back to life.

Comments on Leeuwarden-HF's post say the same glitch routinely affects them, particularly the first time they take out their Heartbeat Sensor in each match.

"I thought I was going crazy [because] my internet is messed up," wrote commenter u/unsullied56. "It actually causes me to get booted out of the lobby sometimes with a server disconnected error that was 100% from their end."

The bug does not appear on the Call of Duty: Modern Warfare Trello board, which developer Infinity Ward uses to update the community on known glitches. It's unclear if Infinity Ward is aware of the glitch.
