@SilentNight2 just for the record, Runemate has been broken on and off the past few days due to updates the client developers made, this isn't due to the game update itself.
Also, to clarify, even if I made the change you outlined, this bug still would have happened. This is a weird bug currently with Runemate where, under very specific circumstances, Runemate isn't able to detect NPCs at all. So the bot wants to deposit stones, but RM is saying the great guardian doesn't exist (which is impossible when RM is returning the correct data) so the bot is just performing the next available action.
For the record, this bug with Runemate not detecting NPCs only happens if you: run Runemate/OSRS normally, close Runemate (without closing the game client), and then re-open Runemate and use the previous game client. Very weird bug, I know, but admins will have it fixed soon. You can avoid the issue by closing both OSRS/Runelite and Runemate whenever you close RM.
Temporarily anyway, like I said admins should have this fixed soon. ^
Anyway yeah I can refund you. Sent you a refund for the 3 sessions.
