I've just upgrading to version 1.8.62.
I logged in and launched my ship from the station. I'm now drifting slowly through space with no energy. I can't steer and have no way to get back to the station, except for /explode.

I believe this happened when I upgraded to version 1.8.61

The bug appears on both my laptop and my desktop machine.

Do you know what ship it is that you have?

It was a Revenant MkIII
It had either a light or medium power cell.

I had to destroy it in order to continue playing.

If it happens again, what info would you find useful/what can I do to help?

Sorry. Forget this report. I think its something to do with my plugins.

Very strange.

My plugin registered an event handler for INVENTORY_ADD in which it calls GetInventoryItemMass(). For some strange reason this appears to be causing the problem if you previously logged out with your ship not docked at a station. I'm not 100% convinced as it makes no sense.

log off and back on

occasionally i drift at 20m/s no control etc its been a bug or a while.

logging off and back on makes no difference. This is 100% reproducible - although it probably won't be if I try to prove it :-)

I solved the problem by removing the INVENTORY_ADD event handler.
