If you have over 9 flagpoles in a map, the upload check will assume your map is supposed to have 18 holes, even if all the flags are assigned to only the first 9 holes.
Steps to Reproduce
Make a nine-hole map where at least one hole has multiple flags
What I expected to happen
Game checks that flags exist for holes 1-9, and will still accept if there are multiple flags in a hole as long as each hole has at least one flag & no flags exist for holes 10-18
What happened
Game checks for if there are exactly 9 flags present. If there are any more, it will assume the map should have 18 holes
Notes / Media
This map has 9 holes, but Hole 2 has two flags.
