Just with the information you gave here it sounds like the map process is bugged. If there's no errors to see, the game runs but nothing happens, it's most likely because the character is stuck there.
As long as the map exist and you know you're on that map, the character should work again after a server restart. This can sometimes take a while though.
If it's stuck in one of the public maps that others can play on, this wouldn't be likely though and something else might be the problem.
