Alright so earlier I logged on, and when I went to Haven 2 (Bazaar,) I noticed something was odd. When I went there, it displayed I was no longer in the guild, that I either was removed or left the guild myself. Now when I brought a non-steam alt, I was able to still use guild chat, and it displayed on the other character that I was in the guild. Something else I noticed when I talked to one of the officers is that when I went to Haven 2 a second time, a message appeared stating I was removed from the guild, (I am not sure if it displayed a name or not though.)
Here are some images showing what I was talking about:
