[bug 1.1a] Zones and Portals bugs - RESOLVED

I'm having issues with portals and zones. I searched for the fix but both this and this is already applied in alpha 1.1. My issue is that when I'm inside a portal thats linked to a zone, then if i look in a certain direction (usually a random direction), the content of the zone is unrendered (btw. i think this is the same issue as Joshua Halls is/was having trouble with).

To make it easier to understand my problem I'll post some pictures.

Here i am inside a portal, liked to a zone.

Then i turn my head slightly to the left, and...
It's gone.

If anyone knows the fix, could u please post it here.
Thanks.
