I just installed the library and tried to access the Account Summary. I got an error for line 1698:

a.upgrades?.baseBuilding?.[0]?.name.trim() == ogl.db.serverData[1] && serverTime.getTime() < a.upgrades.baseBuilding[0].end && (s.querySelector ("strong").innerHTML += `<span>${a[1]+1}</span>`);

_end _cannot be called on an undefined object. That's because _baseBuilding _is undefined because I didn't navigate to buildings after installation. it's just a small problem, should add ? for baseBuilding[0]

thanks

should be fixed now (5.1.0)
