in the latest version on steam, ( main menu says 6.2) the ghost entrances/ladders do not appear in the airship editor, along with the red tint that invalid rooms are supposed to get, thus making troubleshooting where a problem is neigh impossible, I've spent the last hour staring at my ship and repeatedly ripping it apart piece by piece to find the problem to no avail.
for all i know the ship is perfectly valid and the game is having a heart attack.
First bug I've run into so far, and the performance increase is great. Overall 6.2 is a good step forward.
I tried resetting the game multiple times but that didn't help.
This laptop is running windows 8 64-bit, and has piss poor specs otherwise.
4 gigs of ram ( presumable DDR2, not sure it's not mine)
1.7 ghz dual core i-5 processor
the floating coal out the back of the ship is to show that the obviously disconnected parts aren't getting their red tint.
