My sprites are not being created or something

I am making a tank game where you can select different projectiles to shot.

All my projectiles were working fine, but after some time, some of them are not being spawned anymore.

I decided to put all the projectiles sprites on layout and play the preview, and the bugged projectiles are not being created on beggining of layout...

I have no idea what's going on. I'm pretty sure I didnt any modification in that part of game.

Please, send me some mindlight because I cant even describe my problem properly.

Could be many things, but the likely thing is you have a destroy action to get rid of all projectiles so you never see them on start of layout. Are you able to share capx? Probably easy to resolve with the file.

I've solutioned it. Well, manually. I deleted the bugged sprites and made new ones, then replaced them on the sheet.

Could you explain better what could have happened?

Thanx for response.
