Jumping through map?!???

[Particular836]

ok so i made a map with a high level (because i made mountains) and when every i test it out and jump my character goes straight through the mountain and falls down to no where.I made the level to 18,000 and ive made maps with higher level but this never happened.Anyone know how i can fix this?

It might be some strange glitch,or you some how messed up on the Height Map.Try re-making the map,see if that helps~

This has to do with the placement of a portal inside the map. Make sure you set portal settings.
