Weird bug with train relation 38XX

[koeleboe]

Weird bug is happening with train 3882. Probably it has something to do with a train relation being split in GTFS (comes from 2082)? Train arrives in Brussels Zuid at 12:03 and departs at 12:06, but then the wrong times are indicated.

In HAFAS you see the same "weird" bug.

Weird, seems fine now when looking back a couple of days later, so it might also have been a case where some identifier got out of sync between the GTFS data and routeplanning data, or within the hafas data
