If the problem happens because of non-standard settings such as jump height then change them back. The reason for such changes is to allow players to do things they normally are not supposed to be able to do. In other words, in a way the creators did not intend for the game to be played.
If I complain that people here are able and allowed to jump higher than what was intended, and it is an unfair advantage, then I will be told too bad. If however I go somewhere that the mapper didnt intend, because I could jump higher, then I will be told to move or be kicked. Its inconsistent. So if 'intent' is the issue then change the settings back to stanard.
