Decided to try out the Phials method for the day (Though I don't recommend others use this method because while it saves about 250k/hr it cuts the XP/hr by a lot).
Now, it worked very well, but it broke for me twice so far while walking to Phials.
I doubt this is enough info to figure out what happened to the bot but:
It happens after exiting portal and going to unnote at Phials. My character got stuck on the same tile.
My OSRS client was enlarged vertically so the bot wouldn't move the camera around.
It happened while I was away from my pc, so I didn't interrupt anything on accident afaik.
To fix it I had to Enable Mouse and click anything. As soon as I clicked on OSRS, the bot came back to life.
I feel like due to the weird screen shape it could be an issue on my end. Regardless, I hope this helps if it is a universal issue. Thanks for reading.
EDIT:
Bot settings were: Oak Larder, Demon Bulter, and Unnote at Phials.
RuneMate settings are all default except low detail mode is on.
