Road vehicles have wildly inaccurate speeds being shown in 'available vehicles', depots and 'replace vehicles' windows.
Other vehicles are not affected. RVs appear run run at their actual speeds. (picture 1jan)
This is fixed now, it appears to be a bug in upstream commit e6bb9054, I will propagate this issue shortly.
The original acceleration model is relatively unused and I for one don't test with it.
However, they also exhibit strange routing behaviour. I normally have double through stations that allow trucks to pick a vacant bay when they arrive at a truck stop
and this mostly works. V310, this doesn't happen. A group of trucks will pick one bay and end up queueing. Some time later, trucks will pick the other bay.
They also have trouble pathfinding when part of a road is removed. They will move down that dead-end road without realising that it now leads nowhere.
See the enclosed pictures. (2jan and 4jan) I cut the road as the truck on the left starts its journey and it proceeds down the dead-end road.
This confused pathfinding is sometimes quite erratic...but it's as if the truck has decided on its route and will not be aware of the route becoming damaged.
I'm using the recommended YAPF pathfinder and have standard settings (unchanged for years). I can't think of anything else that might be causing this.
I'm back using V29.0 where this problem does not appear. I've also tried a no GRF game and get the same effects with the default road vehicles.
Also tested on 2 different computers with the same results.
As it hasn't been reported I'm worried that it's due to me...
Probably road modification commands should do some cache invalidation of road vehicle paths.
Clearing the cache for all road vehicles would be the simplest answer, though it is a little heavy-handed.
Load balancing between vacant bays is a little more tricky without re-introducing performance issues.
Hello, I've noticed a little bug with tunnel entrance, using 0.31 win64 default blitter/animation (that maybe the problem?), it's like the sprites don't update when zoom or move. See attached screenshot.
Using Nvidia 1080, windows10, windowed (fullscreen same problem).
Edit: Or maybe it's from japan tracks? don't remember having this problems before, road tunnel are fine. Tested and i'ts only that old brick style of tunnel, the modern tunnel is fine too.
Edit2: It was the Monorail Track Replacement 1.0, after removing it, all fine!
It might be worth mentioning it to the GRF author if they are still active, they may not be aware of the issue.
