Rogue baseboards

On my Route I have a board that contains a Junction station where a branch meets the Main line however I have discovered that from all three directions trains will not enter this board. They stop with wheels rotating & I just have to end the session at this point. I thought at first there was a track or signal problem but have concluded it is the base board this junction station is located on. .Today I decided to delete the offending board & rebuild the rogue section but I have never had tris happen before building routes for own use since UTC. I am using TS22 Plus & the Classic Surveyor. I just wonder if any others have has this happen.
This is a new one for me.

My thought is, there was some kind of data corruption in the route that caused that issue. Sometimes, running a Delete Missing Assets can clean up weird things like this.
