I've fixed this. Allow XenoSuite to auto-update.
I've seen many people mention these bugs with Nakuu's team scripts. I've asked many people to provide me scripts so I can try to fix the bugs, but nobody does. Blame them.
Do you mean it is logging out, or really closing Tibia? I fixed the logging out bug; just close all Tibia clients and restart XenoSuite so it will auto-update.
