Patch 11 (Walking, couplers, AI, UI)

Patch 11 is now live with important fixes and quality-of-life improvements:

[h2]Walking[/h2]

[h2]Couplers[/h2]

Fixed un/coupling on foot when cars are off track
Fixed player owned trains refusing to couple in some cases (thanks to player jeanvoilegaz59 for help!)
Fixed distance and positioning of visible couplers when cars are coupled (still not 100% accurate in all cases)
Fixed coupler interaction when there's a derailment sign nearby

[h2]AI[/h2]

Fixed long AI trains sometimes getting stuck at red signals
Fixed AI to not drive too cautiously downhill (at half speed and stopping for no reason)
Fixed AI to use power and brake more quickly (thanks to player kev4ev for help!)
Changed AI to be more careful about not exceeding speed limits
Adjusted AI braking curves again

[h2]User interface[/h2]

Fixed HUD menu to remember if minimap or achievement box was open when returning from the main menu
Fixed speed limit signs, wrong way signs and signals sometimes being outlined for no reason
Fixed minimap teleporting to work when in a train
Fixed derailment notification to display speed correctly

[h2]Track layer[/h2]

Attempted to fix track layer derailment when going forwards and changing to removal mode at speed
Fixed missing generator sound when track layer is in removal mode (broken in the previous patch)
Fixed track visuals to update faster when removing a turnout
Improved collision box to make it easier to go between the track layer and a coupled car

[h2]Miscellaneous[/h2]

Attempted to fix a possible crash after autosaving when using a high time acceleration setting
Fixed slow loco to release brakes faster
Fixed a possible terrain related crash
Fixed a possible physics related crash
Optimized physics calculations
Made level 9 train double headed to prevent stalling at 1% grade
Removed super fuel because it wasn't working properly

The next patch will focus on improving the menus, HUD and controls.
