[1.199] Subgrid dampening does not work if the subgrid has active thrusters

Merii shared this bug 5 months ago
Reported – Awaiting fix

Ship dampeners still do not properly take subgrid mass into account in gravity if the attached subgrid (another ship, usually) has active thrusters.


  1. In a gravity well, take two ships, one of which that could support the mass of the other.
  2. Dock the smaller ship on top of the larger ship using a Connector.
  3. Disable the dampeners of the smaller ship.

Actual behavior:

If the smaller ship's thrusters remain enabled, both ships will begin to drift downward. Disabling the thrusters on the smaller ship makes the thrusters of the larger ship compensate correctly.

This appears to be the case as well if the smaller ship's dampeners are re-enabled - as long as the smaller ship has active thrusters, gravity compensation will fail on the larger ship and it will slowly drift downward.

Expected behavior:

The subgrid mass is correctly taken into account and thrusters can be left enabled with dampeners off on the subgrid.
