Change max level to 91 in the file if you want to be able to use it at 90. It didn't work for me at first, but upon inspecting the file, I saw that max level was set to 86. Seems to be working prettywell now, other than skipping a couple nodes. I'll post back after the run and let you know my results.
Edit: OK, this profile works very well. After only 10 minutes or so, I already have 138 ore in my bag. Thank you for the awesome profile.
