Yes, what you've noticed is unfortunately a part of the game as it stands.

Things drop based on two things:

[1] Whether it's worth spending a cube on it.

[2] Whether you can snipe it and get a cube back which is effectively a free hit.

For the first day or two most people can either cube a boss outright, or those that they can't cube are offering the highest rewards available at the time so it's still relatively effective dropping a cube on them. And sniping can happen from pretty far out in percentage terms.

By the time you hit days 3 - 5 or so, a boss that's worth 2k to 10k points isn't really worth a cube when there are bosses worth 20k or 50k points, so people tend to stop spending cubes on the 2k to 10k type bosses. The only people that still spend cubes on them are people who don't see the 20k and 50k bosses, and they tend to be doing relatively little damage, which means not enough is done to take the boss into free sniping range. Which means they sit there and escape eventually.

It also doesn't help that its a bit of a vicious cycle, but as more bosses start escaping, more people that might have been tempted to throw a cube at it hold back for fear it doesn't drop, which ultimately contributes to more and more of them escaping...
