As I was playing with the Space Shooter demo, I noticed an instance would come up where the sprite for the laser beam would stop appearing while firing it. Even more so however, is that the enemies will start to get stuck on the other end of the screen.
At the same time, one of my projects (Coincidentally, a space shooter), has also been showing problems regarding actor movement, including the inability to move the player's ship.
I've been trying to see if I can diagnose what could be causing this, but so far I'm not sure. I'm making this post so others can be aware.
