I don't receive all trainspotters, at the moment it happens at NL01 for me. Yesterday during the night I only got 2 spotters which should have been 10 regarding the time I was offline during the night. This night I received 6 instead of 10 spotters. Again I was longer than 10 hours offline.
I play also NL201steam over europe and COM6 fast forward. These servers I had 10 spotters to collect at both days.
It is happening for some time now, first I thought I collected them without paying full attention when I did it. At the moment I'm checking my spotters before collecting.
I asked players of my own asso and the other asso's I play with and some say they see the same, not receiving all spotters.
I did send in a ticket about this issue but again a standard answer. Thank you for reporting we will pass it on. Nothing else, can a DEV take a look at it and make sure it is solved with the big upgrade.
