Game freezes when changing music

[thag]

Hello,
I have a problem with music trigger. Every time a unit enters specific region, then a different music (custom implemented) will play in the background, however everytime this happens, the game will lag for a 1 second, but if the unit leaves the region and music changes back to default original music, then there's no lag. Is there any way or script to fix this kind of micro lag?

• Northriver Music
  • Events
    • Unit - A unit enters Northriver town music <gen>
  • Conditions
    • (Entering unit) Equal to HeroUnit
  • Actions
    • Sound - Play Town_Music <gen>
    • Sound - Set music volume to 100.00%
    • Sound - Set music to 100.00%

Its a simple trigger in RPG map, where only one unit can activate it at a time in a large region.

• Northriver Music leave
  • Events
    • Unit - A unit leaves Northriver town music <gen>
  • Conditions
    • (Leaving unit) Equal to HeroUnit
  • Actions
    • Sound - Stop music Weakening in the end
    • Wait 1.00 seconds
    • Sound - Play Music

Everytime the unit enter this region, game will freeze for 1 second, but when u leave region, it won't.

I finally resolved the problem, by swapping over to a newer version of game. probably some old bug in editor.
