Odd, I've never heard these ones before... But I do have some ideas. Will look into this.
If you're botting on RuneLite, please try using the regular client, as RuneLite support still has some bugs.
Otherwise, this sounds like the type of issue that is usually a temporary Runemate bug, often cache related. You may be able to fix it by restarting OSRS & Runemate before trying the bot again. Otherwise, try clearing your OSRS game cache & restarting OSRS/Runemate again (instructions on this page
https://support.runescape.com/hc/en-gb/articles/360001441169-How-to-clear-your-cache-#OSWin).
Feel free to test using the lite version of the bot so you don't get charged while testing.
This also might be a caching bug like above so I'd advise trying the game cache clear as well. But I've never actually heard this one so I'm not sure exactly tbh. Can you let me know if it keeps happening?
