is there limit for using ent_create?

here's my main but the last object that i load using ent_create says can't open file but when i swap it to the
court.mdl position and put it on comment it works. but when it comment it out the court.mdl which is now at the end after i swap them says can't open file again.

anyone knows how to solve this?

//Load the level
level_load(level);
