Sprite disappearing? Possible flashing bug

So this is the 2nd time this has happened to me while building this exact game, and the last time this happened it worked itself out and I don't know how.

Basically my game has a turn based battle system that relies on flashing animation to change the turns back and forth and for some reason after my first attack on the creature the sprite just disappears.

Last time I posted this no one who downloaded the file could replicate the issue and it eventually just went away but now its happening again and I'm not really able to progress on development unless I can get this to work. Any advice would be helpful!

Your link shows "Access denied".

You can run your game in Debug Mode (Shift+F4) and check yourself what happens with the sprite.

Sorry, i messed up the permissions, it should be available now.

I've been running it in debug mode and I can see the sprite is being made invisible but I cant figure out what's doing that. The only events that affect the enemy sprite currently should only cause it to change animations or flash, not change visibility.

OKAY THANK YOU.

It took an extra event to just auto make the layer invisible every time the battle layout loads but it functions and thats all i need.

I didn't realize i could do things with layer names instead of numbers though, so thank you time 2 because that streamlined a lot for me.
