Diagonal sims disappearing again :(

[Tymus Tenk]

I believe I've heard of this being discussed before, but has anyone heard of it being a problem again ... I have an estate of 12 sims all connected together .. on all sides ....all on the Second Life Main Servers ... made up of full, open space & homesteads. In the past i was able to see the sims diagonal to the one I was on.... but recently, the diagonal sim will be visible for a few seconds then disappear.  I remember this happening once before. ... then a rollover seemed to correct it ...but the problem seems to be back.  Anyone know what Im talking about ?  lol   i know it can sound confusing.  I was wondering if anyone has heard of a solution in the works...and maybe why it happens at all.......thanks ;)
