Ok to rephrase, remove the Wait and destroy, create another event 'on animation explosion finished' > destroy
Ooh, sorry for the misunderstanding. That seems to have done the trick :)
One more question if thta's ok. Is is possible to stop the 'bullet behaviour' on the family of obstacles? E.g. On Bullets touched, set bullet speed to 0? The option is there for normal objects but not families.
