I recently bought a new laptop. When I did and came back to runesacpe and private servers some things were different, for example whenever I run a server and log in on the client and walk ANYWHERE it closes out. I can teleport, and do everything else as long as my guy doesn't physically walk. That's a bigger problem then i've had before and probably has an easy fix labeling me stupid. I just need a point in the right direction, any advice would help, I very much would like to start learning how to code (since my brother is currently going to college for that) but I can't without this beginning problem.

Thanks in advance guys


-edit
this is what i get everytime i walk somewhere, on any client, run off any server.
