The "light1" issue is from Q3, so just comment it out instead of using "light 1" that would cause q3map2 to emit flares.
Wave isn't a shader keyword, probably meant to use deformVertexes.
Stage containing only a filename is probably meant to be map.
Some revision messages:
Cache servers for each master server in q3_ui, otherwise servers from last updated master for shown for all Internet# sources.
Play correct team sounds when in spectator mode and following a player.
Check last listener number instead of clc.clientNum in S_AL_HearingThroughEntity so sound work correctly when spectate following a client. (Related to bug 5741.)
When in third person, don't play player's sounds as full volume in Base sound system. OpenAL already does this. (Related to bug 5741.)
