Airplane disappears and reappears during control

This could fatally prevent IFATC from providing good service. All the planes waiting to take off disappear and suddenly reappear. Also, all planes crossing the runway disappear and reappear. Even after the plane disappears after landing, it suddenly appears. If it happens on some planes you might think it’s a problem for them, but this happens on all planes. It was very well connected to the server and some planes looked too good for my frequency and at the time it was too absurd to take pictures. I was so annoyed while I was in control, it was a high traffic situation at the time, and it was such a fatal bug. This bug has happened before. I hope it gets fixed soon☹

I was a tower to OEJN and I’m really sorry if I provided poor service.

Not a new issue. Been around for ages
