Ok either I'm going crazy, or I witnessed a second glitch.

Basically, last time I got my seeD salary, I was seeD level 30. Then, my next salary after that, it said level A back down to 30!

I didn't go up to A from 30 the time before that!

Or did I? Maybe I'm going crazy and not noticing things?

(I was in Shumi village at the time)
