If a lemming get killed while he is lasering, the laserer's sketch remains permanently.

If a lemming get teleported while he is lasering, the laserer's sketch points to the old location for few frames.
I think this is relatively well-known but anyway.
Your showcase animations are always excellent. Thanks for taking the time to make them!

Removed lemming fixed in commit 0e7ea49. Teleporting lemming fixed in commit 50b52b7.
There is still a slight oddity for one frame with a Laserer who goes through a portal. Given that a very specific and unusual setup in the level design is required to achieve this, and it would be a fair bit of effort to make a fix that doesn't risk breaking other things, I'm leaving that case as-is.
