[UDMF] Floor mover trigger issue with music change line def action.
Sev ran into this issue recently in a stream he was hosting on Twitch were he was trying to set up a button that when it was done with its floor moving down, the music changes. However, in the attempt, the music didn't change.
I attempted to recreate this myself and hit the same issue until I looked at the flags and saw a flag for affecting all players was unchecked. when I checked it, the music changed as it should.
after walking Sev through this he requested I make this issue for him as there should be a way for only the player that triggered the floor to move to have the music change for just them.
Included is the wad I used to test things out. UDMF_Musictriggerissue.wad
On this map are 2 buttons set up to move a floor and change music. the red button will change the music for everyone when the floor stops moving. the gold button will not change it for everyone and is set up the way that was causing problems in the stream.
