Mech Centipede started 10 jobs per tick. Huge lag.

[Dzlan]

During Mech raids in which Centipedes are acting as Sappers,
every few seconds on normal speed causes the game to freeze entirely for a few seconds.

Checking out the logs, shows that Centipedes are starting 10 jobs per tick.

Is a list of the Logs.
The only one's causing any issues is right at the bottom.

This has occurred on several different raids. However, I foolishly forgot about logs and would just savescum to prevent the lag inducing event.
