From Raven4277:

When your character is drunk, and slurring words in guild chat, Greenwall throws up an error (I didn't get the exact text but something regarding message corruption and to disable other chat addons) after everything you say until your character stops slurring the text.

Any chance this will ever be fixed?

We can protect against this when we implement Base64 encoding of the messages by applying the following transformations around the Base64 encoding.

• Map 'S' and 's' to alternate characters in the encoded text. On the receiver side, apply the inverse mapping.
• Remove any occurrences of " ...hic!" on the receiver side.
