Just retested this as of current master (and on a new CPU). Without fix: pathfinder is called every tick With fix: pathfinder is called once |
|
I think master...glx22:fix_7670 has the same effect without requiring savegame bump. |

This is a tentative fix for #7670 , but not fully tested. I thought of caching the origin of where the pathfind starts its search. It seems to solve the issue, but I'm not sure this is the right approach.
Problem is best explained here: #7670 (comment)
savegame for testing, requires only 2 vehicles and a giant road network to trigger the issue : https://github.com/OpenTTD/OpenTTD/files/3801034/2.vehicles.only.zip
