This appears to be an issue with Rakshasa. Something I've noticed for awhile but didn't bother to report it until now, aheh.
There seems to be an issue with investigate referring to my char as the previous race they were shapeshifted as instead of the current. An example was I logged into the server as a X, shifted into a Y, went to a new area and investigated a NPC. The NPC said they saw a X moments earlier instead of a Y.
Some testing:
I tried relogging and it still treated me as the previous.
I unshifted and investigated in my base form and it recognized the form I had just been (Y).
I then reshifted into that second form(Y), and it went back to treating me as the first(X)?
