Thank you for noticing that, we're working on it.

As to the Missile exploding, I'm going to guess you haven't set Extra Parameter 8 yet so it's defaulting to 0 (instant destruction). To use Extra Parameters effectively, you need to set values to quite a number of them, in the case of Missiles Extra Parameter 8 is vital as it controls the lifespan of a Missile. When Extra Parameter 1 is 0, it will not accept any other Extra Parameters and it defaults to the Missile's in-game settings. Any other values than 1 means you are committed to using other Extra Parameters. If you did set Extra Parameter 8 to a value, then there may be a problem. I suggest setting it to 30-50 as a test. I also suggest changing Extra Parameters 2 and 3 to control the speed of the Missile.

You don't have to set all of them, just the ones that you want. Think of the Extra Parameters as a way to rewrite a part's function. For example, using the Energy Egg, you want it to shoot out very fast but slow to a crawl later and shoot Ion Rings in a line at the player. The Eggs cannot be hit. The setup would look something like this:

Extra Parameter 1 = 1 (Allow Extra Parameters)
Extra Parameter 2 = 3000 (Initial Speed)
Extra Parameter 3 = 150 (Fading Speed)
Extra Parameter 5 = 1 (Shrapnel aims at player, line)
Extra Parameter 6 = 24 (Ion Ring shrapnel)
Extra Parameter 7 = -2 (Intangible)
Extra Parameter 8 = 40 (Short life)

This will run you 2 events. As you notice, Extra Parameter 4 is omitted. This is because I don't want the Egg to curve.

Hopefully that gives a better explanation. You could also look at Section 1 of the Extra Parameter tutorial for a recap. =)
