On the stable branch any arrow that is fired from a bow will stick into the environment and stay there.
It will never decay or de-spawn, even if in a ruined state.
This will cause a buildup of arrows in the environment, leading potentially to performance drops
Fire an arrow into the environment.
Come back a few days later to find it still there in the same condition you left it at.
This could be one of the things contributing to slight performance drops as of late.
Hello Flimflamm and thank you for the report.
The issue has been confirmed and scheduled for a fix.
