Oh sorry, you're right I should've been more clear. What I meant was that there are times when webwalking doesn't work for any script I try, including ones I've made myself or ones on the SDN, so I'm assuming it's a problem with OSBot.
I'm not sure, it might be fixed by restarting the client, I'll have to test it next time but if it's persistent then next time it occurs I'll definitely take a screenshot of the logger and share it
