GreaseMonkey's Script gone UNSTABLE

http://www.kongregate.com/games/mastermax/ultimate-assassin-3-level-pack?tab=achievements

Don't know if anyone sees it, but the hacks are for a game called "Action" and not the one I gave the link for.

The same with this one

Again, not sure about it.

What's going on? Can it be fixed?

No clue what happened here. ? Looks like the ?tab=achievements might be throwing it off.

Could be an issue with the titles as well...
