0002350: Portals are assumed to be skyboxes
In GZDoom 1.8.0 and later, using type 0 portals will not interact with the sky at all, displaying the portal properly and using the normal sky texture or sky box.

In Zandronum 3.0, type 0 portals work but are also turned into sky boxes, rendering the portal normally in addition to rendering it again as part of the sky.

In 2.1, such portals flat-out fatal error the program.

This seems to be caused by an ancient bug fix:'https://bitbucket.org/Torr_Samaho/zandronum/commits/61bf08da15a659c68779c9496ad3f97349b2f66f [^]'

I'll have to further investigate how to fix this without reintroducing the old bug.

portaltest.wad seems to work properly now, but I'm not sure if SkyViewpoint and SkyPicker skill work as intended online. Can somebody check this?

I tested portaltest.wad with a lan server with 3.0-alpha-150831-1814 and it seems to work properly.
