When trying to access Nether after building the portal I can't land in a superficie. 

I keep falling till I reach an empty cenario that has not loaded!

When I die and get back to Earth the cenario are all messed up, with blank and empty spaces that can't load and I have to reset the plataform. This keep hapening all the time and I can't access Nether because the cenaio doesn't load completley and I fall dyieng immediatly after leaving the portal

@anyone else?? 

Help please! 

Thanks
