Hi, I dmed you a while ago to debug and/or try to get more info but didn't receive any response unfortunately. I've looked into it some more either way, and while I'm not experiencing 15 second delays on my end, I did notice some inefficiencies that would probably cause a lot of delay under certain circumstances. This might have been what you were experiencing.
I released an update last night that should make the bot more efficient and reduce delays that might cause this, and I have some more updates plans to boost processing effciency more.
Please feel free to dm me or post in the bot thread if you encounter any other issues as it's easier to have a discussion & I'm very willing to help debug.
