Vendoring doesn't work in Ryftomate 1.0.1.785. We are looking at this and will have a release with a fix over the next day or so. Meanwhile please empty your bags manually. Sorry for the problems this causes.
I was about to quote you, and you did this post in the exact moment. When the bot tries to vendor it just teleports to the near soul portal, right?
The error says about trying to write over protected memory, so this has nothing to do with Rift? As this does not trigger unstuck tool's cooldown, it looks like Trion's doings. Am i wrong?
