Discuss the new AI features ("NoAI") introduced into OpenTTD 0.7, allowing you to implement custom AIs, and the new Game Scripts available in OpenTTD 1.2 and higher.
I find it interesting that one crossing made by your AI is using bridge and one is not. Is it by random or by the funds available? The road and rail pieces don't have built date, but stations do and it looks by the owner of roads/stations that the road was there first.
Other than that, or maybe thanks to that, your AI is in shared lead in the operating profit graph in my 14 AI test game. At year 1967 started from 1953.
I had to check the code since it's almost a year since I worked on this but it seems that it depends on the pathfinder costs whether it chooses to build a bridge or not.
Besides that since WormAI doesn't yet do road transport I guess it doesn't really matter too much what it chooses. Especially if it's competing against other AI's it might be a strategy to lower competitor's profits.
For normal users it might be annoying so maybe I should add a setting to disallow building tracks across roads.

Maybe I care too much about ethics, but I file that under unfair competition to on purpose use rail/road crossings to block road traffic. It is very hard for other AIs to do anything about it if they didn't build the road themselves. If it is my AI that built the road, I can (and do) replace it with a bridge when there is a bus/truck crash event, but if there is a fellow road AI that built the road and does not care about upgrading it to a bridge, then it is not so much I can do about it.

A new version of WormAI is available on bananas.
Only changes in aircraft handling this time. WormAI should now be better at handling the World Airliners Set and other NewGRF that have higher costs for large and longer range aircraft.
Changelog
Version 7, 2017-04-16
Fix: Not checking air route range at startup under certain conditions.
Change: Adjust maximum distance for air routes when we have limited money.
Change: Adjust aircraft selection when we have limited funds and high prices of longer range aircraft.

Thanks for the report.
Assuming this is the save that caused the error. Do you also have a savegame from a little earlier that does load or at least mapsize and rough estimate about number of vehicles.
WormAI doing a bad clean up job and creating some roller coaster rail routes. Savegame attached. The settings are borrowed from server 7 of btpro, they're probably influencing some of the weird misbehaviours.
The rollercoaster lines were caused by a pathfinding bug in the rail pathfinder, now fixed. Not deleting tracks was most likely caused by running out of money. This should be less likely to happen now because of using RemoveRailTrack instead of DemolishTile where possible.
Changelog
Version 8, 2019-09-09
Fix: Determination of 90 degree turn in rail pathfinder was wrong causing rollercoaster tracks and difficulties finding a path.
Fix: Remove rail tracks by using RemoveRailTrack as much as possible since that is cheaper than using DemolishTile which makes it less likely that we run out of money early in the game with a failed train route.
Fix: Not building airports in spots where the noise level will equal the maximum allowed noise level.
Fix: Take station spread setting into account when determining best airport type.
Add: Manage over saturated air routes by either removing planes from route or upgrading airports.
Add: Upgrade airports to International airports in certain cases.
Add: Regular checks that industries we use on a rail route are still accepting/producing our cargo. If not we will sell the vehicles and close the route.
Add: Extra pathfinding penalties to make it less likely the pathfinder continues a path far away from our destination.
Change: Improve finding airport spots adding towns to blacklist more often and only checking towns within distance limits.
Change: Adjust max aircraft route distance in early starting games depending on plane speed and reliability.
Change: Rail: Increase length of train routes if we have enough money.
Change: Lower minimum town for airport size in easy setting from 2500 to 1500.
Change: Use Graph.AyStar version 6 instead of version 4.
Change: Moved repository and issue tracker to Github.
Did you manually download the AI's instead of using the in game content download?
In that case you also need to manually download all required AI libraries including the dependencies of those libraries. Although, I'm not sure if that is still possible.
In the case of WormAI that means:
- Superlib version 40 (which needs several other libraries)
- AILib.List version 3
