Since the new update, I'm not able to keep a charged weapon (press and hold attack button) for more than a few seconds. Used to be I could hold onto it for as long as I needed. Now, it will release at inopportune times, sometimes getting me into trouble.
I checked for lag -- the 'signal strength' bars in the corner of the window is at full.
My computer hasn't changed; the behaviour of the game has. Furthermore, it's changed after the game tells me that I'm downloading new software and patching Spiral Knights.
I used to be quite good at running around and making strategic hits, dodging blows. Now, I daren't charge my sword else it might 'let go' at the wrong time.
I'll try replacing the LWJGL libraries with a newer or older version, since this seems to be a problem with sensing input.
Might be somthing with your comp.. couse I dont have this problem..
