1) I think this calls for another patch (there is probably a SETMAPSUN preview left in the maplist.script)
2) did you use the swingdoor for movertype?
I think these have a limitation where you can only rotate them by the yaw (green one on the gizmo) when placing them
3) this might be because of the limited lightmap size - or the lights position
(without looking at your map I can only guess)
4.. or 5?) align to grid
you can align a selected entity to the grid by pressing [
(it might help .. or make things worse)
6) I think these was not added to the zonetypes (rain was a last minute thing)
here is how you can make one:
- press V and draw a zone
- select it and enter the following command: MT rain
7) these are only displayed in debug mode (by default in preview mode you are in debug mode)
I guess these should be patched out to not annoy people - but they don't mean anything serious
8) so far there is only a command to remove all your guns: NOGUN
I need to add a patch for this too
