I'll go from Order Bot to ATB, then back to Order Bot and the client crashes. I deleted the entire previous folder, redownloaded RB. Remembered to Unblock, extracted, redownloaded ATB, etc and after a while, the issue came back. I'm not a programmer, but it may be Kefka and RB are having a fight. I don't know which needs a swift kick in the pants.
If you can reproduce it with kupo then its a rebornbuddy issue. Otherwise contact the developer of the routine.
I def put it before the dev, then switched to Kupo. Def have some errors. The log is too large to attach, I cut a fair bit out of the middle (PoTD zoomzoom), but I looked it over and it all looked like repeats.
