Single spawn call somehow spawns two actors?
I have noticed recently that a single 'Spawn Actor' behaviour can spawn, what appears to be, two actors exactly aligned on top of one another.
I have created a simple scene to test this, with only two actors. One is a 'Spawner' which is visible on the left-hand edge of the screen and has one rule that says:
Timer: Every 3 seconds Spawn Actor 'Mover' in front of actor with all 0's for location and direction - all relative to the actor.
The second actor is the 'Mover' which has two backstage elements:
Move: Direction 0 relative to scene at Speed 100
Rule: If self.position.x is off the screen [ >500 in this case] Destroy this actor
I only noticed this bug/issue because I was using a png image with some simple transparency and every so often the transparencey would look too dark.
The alpha value of the above 'Mover' is set to 50% and every 2-3 spawns the colour of the mover is twice as dense as the previously spawned actors - this says to me that there are actually two actors being spawned exactly on top of one another.
Has anyone else seen this? PC issue only?
