A certain portion of messages typed in guild chat since the patch today are coming back "no such player." The first few times that it happened, I thought I'd typed /r by mistake so I've been watching myself for errors and it's doing it periodically with no error on my part.
It's happening often enough that chatting with guildmates can become aggravating when it decides that the guild doesn't exist breifly.
Also: Typing /g and then one of the things that is now turned into an /e command now emotes it where you are instead of giving you a "lol" or a ":)" in guild chat.
Aside from making you suddenly look insane to anyone nearby, it would be nice if the /g could override text that is turned into a /e command now so that if either emotes it in guild chat (like typing /g /e before your text before) or if it would let the text go to guild chat as is.
After a bunch of testing and chatting in guild chat, it seems the two bugs are the same bug.
It's dropping guild messages if you type "lol" or another message that now auto-emotes if there is other text after it because it's treating it as though you were laughing at the sentence after it (and the text in the sentence is not a player's name.) Same as /lol [playername] previously, but now that it doesn't require the / it's all derpy. Same thing happens if you type "lol" at the start of a sentence in main chat. If whatever follows the lol isn't a player's name... it thinks you're trying to laugh at someone and it drops the message.
