This is a weak attempt to solve a race condition between modules loading
and cmd_use being fired. Upon startup, saved configurations, running
resource scripts, and running commands will sometimes jump ahead of the
module loading procedure.
I have not discovered where the race actually is and how to cause the
race to happen. However, the timing seems to be fairly close to a second;
by waiting three seconds after trying use again, we seem to be in the
clear, at least according to testing.
Fixes#4549, but better solutions are welcome!
