Title: The big ship is caught in the low bridge.
Post by: Ranran(retired) on June 16, 2020, 04:02:07 PM
A large ship that automatically selected a route and tried to pass under a low bridge was caught by the bridge and could not move anymore. (´・ω・`)
It fits the bridge and can't move north or south.

And I'm plagued with spam calling for their help.

Check the coordinates on the brdgewater server.

Thank you for the report. I am not sure why your post was marked as awaiting approval.

Given that online games are non-static and I cannot always get around to finding issues like this immediately, it would help if you could upload the saved game in which this state can be reproduced. Thank you.

Someone changed permissions: (https://i.imgur.com/htJT903.png)

I believe I have fixed them.

Please let me know if it happens again or in any other board and I'll take a look. :)

I know someone recently changes some permissions, I've forgotten who and I'm too lazy to go look up the thread, but it happens. lol. We can fix as we find :)

A small remark, but this very thing happened 2005 with the Storebæltsbridge in Denmark. A drunk 1st officer thought he could get the boat under the low part of the bridge, but shaved the entire top off the ship. Search for "Karen Danielsen accident" :P

Similarly in Jacksonville, Florida in 2016.
QuoteA river cruise ship hit Jacksonville's Main Street bridge Friday night, forcing it to be shut down... its funnel hit the span...

I have prepared a saved game (https://drive.google.com/file/d/19sJUQJCSXlgeZr3GtVuZs00REttj5V7s/view?usp=sharing) that can reproduce this. Depart the ship in the depot and observe it. You can see the ship caught on the bridge by the idiot steering.  :-X

With this saved game, there is no route that goes through the bridge, but the server example can bypass it.

Thank you for the reproduction case: that is most helpful. I believe that I have now fixed this; I should be grateful if you could re-test with the next nightly build.

This seems to have affected all vehicles at all low-clearance bridges, not just large ships.

Thank you for the report. I believe that I have now fixed this; I should be grateful if you could re-test with to-morrow's nightly build.
