Hi!
Has anybody else had the problem of F-Link beacons getting lost completely? I recently decided that 3 teleports are not enough and bought two additional F-Links. After some playing, 3 of my 5 beacons seem to be completely missing; at least I cannot find them anymore in any region.

It also happened to me that one of my previously three F-Links didn't work anymore when I went from Shamazaar to Talanzaar. I could use it, but the computer voice would tell me that there is a malfunction due to an ionic overload or something.
I read that if you place the F-Link "exit" in one region and enter another, you can't use it, but I hadn't placed it at all. So, I went back to Shamazaar, where it worked again, went back to Talanzaar, and again it was still working.
So, I guess it's either a bug, or maybe some kind of weird feature, but in any case the F-Links don't seem to be broken permanently.
