The bot does not stand exactly at the center of the goal. The distance from the goal to the wall is less than 64, but the distance from the bot to the wall is greater than 64.
I fixed the problem now and commited it to the SVN.
Priorities of ROUTE goals were ignored. It will be fixed in the next Omni-bot version, or you can build it now from GitHub.
The 1944_nordwind map automatically changes spawns just after a player joins the game, so you have to add yield() before ChangeSpawnPoint.
TraceLine does not hit anything at the beginning of the game because the construction materials are not there until the path is destroyed.
But you can set entity name instead of trace:
/bot goal_setproperty entityname axispath1_toi
