I think i am having the same problem, i am using one of Botanist dungeon farming profiles (HOL with mail). After the update it no longer wants to send mail to my bank char, tbh mine does not even open the mailbox even though its clearly written in the .xml of the profile. This profile used to work yesterday and since its made by Botanist there should be no screw up on the profile making part.
Might as well write to him on skype, but after i watch a bit and try to fix the problem on my own. So far i think it might be related to the remove of the option to turn off the auto vendor function, because if you want to turn it off and use a vendor and mailbox that you want to show how do you do it? I might be totally off though which will be probably the case.
P.S. We are not allowed to share previous version because of perma ban on forums (I think its some law restriction or something)
