YueXiao Setup Problems

[CxCxC]

Hello everyone,

I am having some problems with setting up the YueXiao :{maybe the springs have become looser}
-I am not able to corner cut{forward} even at 45 degrees and there are too many lockups than they were earlier {at stock tensions}

The cube is locking up : the corners are NOT catching onto the centres, the cube itself is locking up

Please help!!!

Is this gap on other cubes this much as well?o_O
And does everyone's' puzzles' plastic feel soft as well or is it only the teal one?.....
And does the stickerless YueXiao, black one and the other colored cubes feel different?

The lockups right now are REALLY frustrating.
