Map

Basics

No errors
Area under flag is indestructible with an area of at least 5x5 blocks.
The bases have their own team chests.
Map is inescapable - walls and floor should be made of indestructible nodes.
Proper build-time barriers
Functional treasure chests
Flags can be captured without issues
Map is free of other general "bugs"
