1. Green/Red prize boxes are dropping hearts.
I am aware that this is a pretty well-known bug after that so called 'fix visually empty heart boxes' patch. Each time you encounter one, do us all a favour: F2 bug report.

2. Devilite projectile glitch
This is just annoying, doesn't really effect anything. Please remove the box around those chairs devilites throw. I don't want to see them.

3. LD loadout thingy
You need to scroll to see all of them? Nice one.

4. Danger Mission C42
That giant Toxioiler in the very last room takes damage when using guns like Sentenza and shooting at the right spot. It's an easy mission and doesn't need to be any easier.

5. Danger Mission GitM
Last room of the first depth standing at the spot where the Guard will spawn and pressing the respective button that makes the character go backwards in whatever frame of reference it exists in will enable you skip the last part glitching through the gates. GitM is the easiest of all Danger Missions, where's danger when you can skip it?

6. Proto Shield unable to shield bump
Not sure if this was intended or just another silly bug, an individual is able to shield bump with the same useless 0* Force Buckler but not Proto Shield. Why?

7. Spirit not listening to its master
Yes, it still exists. Why not?

8. Occasional spirit glitch
Not sure the cause but once my spirit kept using the skill automatically each time after it has been cooled down. I don't want this happening!

9. UI problem
This bug has been alive since lest year; just not as severe. Having attack set to mouse buttons whilst being near some kind of entity that brings up a GUI with another GUI opened will activate that GUI nearby which is not meant to be activated. (Alright)
For instance having "Character" GUI opened in front of AH and wanting to switch to "costume" on the navigation ribbon above will also bring up AH's GUI. Problem seems to only occur when attack is set to left click[?]. I don't know.

10. DBB glitch
Doesn't effect game play, whenever someone uses DBB it brings out a T2 jelly spike attack right at spawn room (where arm arensal is).

11. Ultimate Black Screen of Doom
No one likes this glitch and I assume it has been alive since beta. Whenever a person disconnects on the elevator while it's proceeding he/she'll be unable to login anymore. It shows that the person has (friend xxx logged on) however the person will only see a black screen. Nothing can be done besides quitting the mission. Got this in UFSC once and made me unhappy for a few minutes. Why?!
