@kukimuki1234 I advise contacting A developer through the Contact Link and explain your problem through a message. As a moderator, I'm unable to help you, which is why I suggest the above.

@Squirrel when you are already here i wana to tell you that my simpleplanes game wont load downloaded planes

@Squirrel Very true.

The limit is in place, due to users complaining about the amount of mass produced planes with little quality. The rule was discussed between moderators and developers before being set in stone, all of which agreed the site would benefit from such a rule as users will be more likely to spend more time on aircraft, thus increasing their quality.
.
Unless there's some sort of revolution, which I doubt there will be because of the number of users agreeing with the change, I can't say the rule is going to change anytime soon.
