If bots are acting strange it could be as a result of a recent game update or similar. Before starting any more bots, check announcements to see if the client is down. If it is, wait for further instruction.
If the client is online, try restarting both RuneMate and OSRS. Make sure to close all RuneMate and OSRS clients to ensure everything is updates when they're restarted.
If you're having still issues with bots "not doing anything" then uninstall RuneMate, restart your PC, then reinstall RuneMate. It's not known what the issues are and how they are fixed, but generally reinstalling and restarting seems to do the trick.
