Hello,
In my server many players are sometimes having problems regarding checkpoints:

1. case: If I create a checkpoint, the checkpoint can be seen ingame, but there isn't a map icon (red blip).
2. case: If I create a checkpoint, it cannot be seen ingame, but there is a map icon.

I have already searched for this problem, but I haven't found something.
What could be the reason for these problems?
